Backported sbxfi driver (UNTESTED!)

Backported sbxfi driver (UNTESTED!)

[Takashi Iwai]

Hi,

$SUBJECT is now on my sound-unstable git tree:
    git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-unstable-2.6.git
together with other experimental patches.

If you're using 2.6.27-rc* git tree, pull the master branch of the
tree above into yours, and run make oldconfig.  That is,
    % cd /your/git-tree
    % git pull git://...../sound-unstable-2.6.git master

If you are not using 2.6.27-rc*, or not familiar with git, you can try
alsa-driver-unstable snapshot tarball available at
    ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/
Run configure, make and make install as usual ALSA-driver tarball.

(I didn't check whether the tarball correctly includes the sbxfi
 stuff.  It should have been generated automatically.  If not, wait
 for a while.  If it still doesn't include sbxfi code, please report.
 I'll fix it tomorrow morning.)

The driver is built only for 2.6.26 or later.  If you have an older
kernel, edit alsa-driver*/kconfig-vers and change the version of
CONFIG_SND_SBXFI to 2.6.24 or whatever you want.  Then run
./gitcompile, instead of configure in this case to update the
configure script.

**NOTE**
The driver is totally untested.  It's just compiled without errors,
but not reviewed after a quick writing.  So, don't expect it ever runs
at the first try.  A crash is highly possible.

There are some build conditions found in sound/pci/sbxfi/sbxfi.c,
starting with XXX_*.  You can change it if you want.  As default, it's
for non-fullduplex but accept different rates.  Not sure whether this
works at all.

Any test- (and better debugging-) reports are appreciated.


thanks,

Takashi

Thank you, will test this later. As coincidental as it seems I pulled my
X-Fi Prelude from my machine last night during cleaning, and never
bothered reinstalling it as I had a bit of lost hope. This is
definitely a huge start.

All of us pushing Creative to release some specs without a ridiculous
NDA would be a big next step.

Cheers,

Bren

I'm using fedora 9 with 2.6.26.5.

Should I just be able to download 

ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-unstable-snapshot.tar.bz2

configure and make install it and that should be it?  I mean, do I need
to do anything with my modprobe.conf?

This is what I had when I had an emu10k1 card, is this driver called
emu20k1?

Hello Takashi,

I will have plenty of patches for this fairly soon. Stay tuned.

Hmm,

I have a fedora 9 machine and I installed your alsa-driver snapshot,
which does have snd-sbxfi.

However, I am getting tons of errors

There might be some extra info in the emu20k1.h file there.
I do not have much time, but I will update the emu20k1.h file with any
register info people need.

Kind Regards

Nevermind, 

I got it to compile/install on my fedora machine, and the modules load.
However, when I run "alsamixer" or click on gnome's mixer applet, it
locks my entire system.  I used your tarball from your site... sbxfi is
loaded, etc.

Re: Backported sbxfi driver (UNTESTED!)

[Ted T. Logian]

Sorry for the multiple posts, but once I rmmod snd-sbxfi, running mixer
does fine.  It seems if I have snd-sbxfi loaded and I run alsamixer, it
locks the entire system.

So, do you mean loading the driver itself doesn't lock up?  If so,
it's better than I expected.

Did you run ever PCM playback/capture before that?  This is more
dangerous :)

Also, please give your hardware details, as there are different models
for X-Fi, and some are handled pretty differently.

I think perhaps from uninstalling pulseaudio I got further.  I can use
mixer now, and it even has a "Master" device, but nothing else...

however, I do get a lock up later.

I get this from running aplay, too, if this helps...

Thanks!  That's rather a stupid bug.
The patch is below.

Hello, I have tried the driver with the fix you provided, but I couldn't get
anything. Kernel panic on any attempt to use sound or mixer. Also kernel
panic several seconds after Xorg starts. Each crash causes either hang or
reboot so I couldn't get any error messages. If there are some logs left,
please tell me where they are and I'll send them to you.
My card is X-Fi Platinum Fatality Champion Series.

For testing, first try without X but just use Linux console, so that
you have a better chance to see Oops messages.  It's pretty important
to see whether it's an Oops or a panic.  Also, double-check whether
you really installed the corrected drivers.  Often it's missing in the
right place by stupid reasons.

For first tests, don't use any sound server.  Try with aplay like:
	% aplay -Dhw foo.wav
Try first 96kHz samples, 48kHz samples, and then others.


thanks,

Takashi

Tak,

I just wanted to make sure you knew of the different types of sbxfi
cards.

For instance, I have this one:
http://www.geeks.com/details.asp?invtid=SB0670-BULK&cat=SND

It's still emu20k1.  However, it is impossible to use with creative's
drivers, as it always causes a lockup, but it works with oss4 drivers.

I don't know if this matters to you at all, but I wanted to let you know
in case it affected how the driver progressed to be compatible with the
most emu20k1 cards.

Yeah, especially Vista-compatible cards require a very strange
initialization sequence, as you find in the source code...

Does it lock after loading the driver?
If not, what does /proc/asound/cards shows?  Also, show the output of
"lspci -nv" for the device, and "lspci -xvvv" before and after loading
the driver.

I'm afraid it's UAA (vista-compatible) type.  If so, maybe something
is wrong in the initialization, or it takes a wrong port address
(BAR), etc...

Indeed, there are really different models with emu20k1...

Re: Backported sbxfi driver (UNTESTED!)

[Vedran Miletić]

What does this mean? That there are X-Fi cards which aren't Vista-compatible?
Also, shouldn't UAA cards work with hda-intel driver with specific
patch for Creative?

X-Fi cards that are Vista compatible boot up in hda-intel mode, so yes,
we could provide support in the hda-intel driver for them.
The features would be limited, but the user would get some sound.

Attaching files you requested.
I don't have 96000Hz samples, tried 22KHz - reboot.
Attempt to load module while Xorg is running causes reboot.
Note that you should use latest mercurial oss to port - earlier versions 
have conflict with drivers like nvidia.
alsamixer shows only master but that probably because asound.conf 
deosn't contain needed info (I usually use system-config-soundcard to 
write all that needed to asound.conf but I can't do it since Xorg with 
sbxfi don't work).

The BARs change when one switches from UAA (the default on some cards)
to XFi mode. You will probably have to provide some method for
correcting this after the change.

The OSS driver seems to overwrite the old values of BAR1-5...

OK, then this sounds like the same symptom as Ted's.
Could you give the information described in my last followup to Ted's
post?

With this patch, the driver does output audio, but the DAC dies and we
only get noise. Going to try to whack at this with a larger hammer, it's
a fairly obvious bug, it just needs some debugging. The noise sounds
like the write pointer is off-by-one; it sort of resembles the source
audio.

Some patches for mixer stuff are coming soon (next few hours
probably)... as well as chip revision detection and some other
niceities.

OK, good to hear that it's not always locking up.

Great.  I'm looking forward to your patches.

Meanwhile, the patch below might improve something.
Basically test sets the DMA mask, and use the continuous pages instead of
SG buffers (in case it's the error cause).
Give it a try.  (And I'll update the git tree, too).

Also, try different XXX_* flags in sbxfi.c.  The default setting isn't
completely identical with OSS v4 driver.


thanks,

Takashi

Hello,

Serial console output from my try with this driver in various modes:

nenolod@petrie:~$ aplay -D hw:2,0 ~/13\ -\ Emerge\ \(Junkie\ XL\ Remix
\)\ \[Explicit\].wav 
Playing WAVE '/home/nenolod/13 - Emerge (Junkie XL Remix)
[Explicit].wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
XFi DAC reset timeout
XFi DAC reset timeout
XFi DAC reset timeout
XFi DAC reset timeout
XFi DAC reset timeout
XFi DAC reset timeout
^C
<system hardlocks on interrupt>

Noise is now on the right channel only.

It might make more sense to poll for the DAC reset in the interrupt
handler. I have noticed that the card generates an interrupt request in
Windows once the DAC is online.

Something leads me to believe that the DMA mask is 32 bits, but given
that the behaviour is similar in both instances, I am unsure.

Hello,

Actually, I am certain that the DMA mask is 32 bits.

Could you build with XXX_CONST_TIMER defined?  This will disable the
adaptive timer-resolution handling I added to the driver, which doesn't
exist in OSS sbxfi code at all.

Does it mean that the left channel plays normally as expected?
Also, which sample rate are you using?  I'm curious whether the sample
rate tracking is correct...

Interesting...  Maybe putting some debug prints in interrupt handler
and else would help a bit for more understanding.

This isn't a critical issue right now.  It can be figured out safely
later.

Also, could you show the hardware information I asked in other posts?
There are certainly cases that the driver works and hangs.  The
difference likely comes from the board type, I guess.

Typo: it reads XXX_CONST_TICKS.

No change in behaviour. It survives a little longer, but then the system
hardlocks... without me even touching the keyboard even.

No. The left channel is silent.

I am now actually 100% positive the DMA mask is 32 bits.

By the way, it's an original X-Fi in this case (I have others to test

This can be a spin deadlock I fixed today.
Could you try the latest sound-unstable GIT or snapshot tarball?

Also, now the driver has "debug" module option.  As default, it's 1,
and the driver shows some debug messages.  When it's 2, it shows more
often, e.g. at each IRQ.  When it's 3, it shows all register accesses.

The debug option can be changed even dynamically via sysfs.  Write
/sys/modules/snd_sbxfi/parameters/debug file as root,
	# echo 3 > /sys/modules/..../debug

Just a note before I go to bed :)

The sound-unstable tree contains the HD-audio X-Fi support, but right
now it's disabled due to possible conflicts of drivers.
Just uncomment the corresponding entries in PCI entries of
sound/pci/hda_intel.c.

FYI, that fix was also broken, and I forgot to push the fix of the
fix.  My bad. 

It should have been fixed now.

problems with fedora 11 and pulseaudio and svn x-fi driver

[Ted T. Logan]

Hello,

I upgraded to fedora 11 with PA 9.15 and got the svn alsa-driver and
installed it for the x-fi driver.

The problem is, with pulseaudio, i get a pop every few seconds
like, every 3 seconds, "pop" and it does it over and over and over

I seem to get no sound at all with the card if I bypass pulse

What can I do?

Re: problems with fedora 11 and pulseaudio and svn x-fi driver

[Ted T. Logan]

I killed pulseaudio and the problem is the same as far as every few
seconds, just a different sound.  it seems to be the xfi driver.

I did not have this problem with XFiDrv_Linux_Public_US_1.00.tar.gz
however, I am trying to get away from that driver because of other
issues.

Thanks!

Please be more specific, what apps did you test and how, and on which
hardware, with which alsa-driver.  There is no svn alsa-driver at
all, at least, as I know of.

If it's emu20k1 chip (not emu20k2), try use_system_timer=1 module
option snd-ctxfi driver.  This will take the timer management back to
the old one using the system timer.

"ticks" with latest x-fi driver

[Ted T. Logan]

Hello,

I do not have this problem with:

XFiDrv_Linux_Public_US_1.00.tar.gz

but I tried the latest driver from:

ftp://kernel.org/pub/linux/kernel/people/tiwai/snapshot/

and I get a "tick" every second or two during playback with ANY
application.

Fedora 11.  sb0670 emu20k1.

What to do?

I finally managed to play music over xmms with this driver.
I needed to modify something, because most music is 44100Hz and the driver did
not work with this rate.

It also needs to run in 48000Hz mode or else it will playback way to slow.
I think this flag in ratec switches to 96KHz mode in the X-Fi, in windows this
mode is only available in Audio creation mode, so it must be handled in a
special way somehow.

Great work with the driver, finally I have sound under linux as creative's
driver only oopsed the kernel for me :)

So, XXX_96K_ONLY doesn't work well?

Thanks, good to know ;)

And, which X-Fi model do you have?
Please show the lspci -nv output, too.

Interesting, XXX_96K_ONLY also works, just XXX_CONT_RATE doesn't.

It's just speculation on my part, but as I just played around with the 
flag it didn't seem to do anything, at least with 44100Hz input.
Otherwise the code I patched in just makes sure ratec is set at all when 
playing back at 44100Hz, otherwise playback in xmms just hangs.

I've got the X-Fi Elite Pro.
That's The one with the external In/Out box.

Speaking of which, the headphone jack on it does not output a signal 
yet, the signal only goes to line out.

There's some relais on the card that seem to switch these, they click 
multiple times with the windows driver and not all all with yours, I 
think that's the reason :)

Original OSS driver doesn't output to external block also, so it

The values for port->conv[0] and [1] values in sbxfi_playback_open()
might play some role.  It's I2SA_L and I2SA_R, alias DAI_CH_I2SAL
and DAI_CH_I2SAR, as default.  You can try other values, such as,
DAI_CH_I2SBL, DAI_CH_I2SA1L, and so on.

Hmm, it seems broken for older kernels right now.
The easy workaround is to pass --with-cards=sbxfi to configure.

Anyway, I'll fix it now.

Hey, man, this is cool! Plays just fine (volume ok, speed ok, no 
glitches) with 96000, 48000, 44100, 22050, 16/24 bit, Stereo and Mono!! 
I didn't change anything in the source code, so I don't use system 
timer. Yes!!

Could be due to 96kHz base-rate?  Try base_rate=48000.
If you get still problems, please show the kernel logs with debug=2.

BTW, the jack.c compile error should have been fixed now (hopefully).
Let me know if you still have the build errors.


thanks,

Takashi

In both cases, check the period_size and buffer_size values (shown in
the kernel message, or /proc/asound/card0/pcm0p/sub0/hw_params).
And, try to aplay with these parameters, whether you get the similar
problem.

	% aplay -v --period-size=xxx --buffer-size=yyy foo.wav

Re: Backported sbxfi driver (UNTESTED!)

[Bjoern Olausson]

Just wanted to ask if someone has some good wav files at different
samplerates mono/stereo etc etc [for all cases] (maybe with some voice
instead of the sinus sound I am using.)

Would be nice if we could make our tests based on the same wav files.

Would make it easier to compare the results.

Kind regards

You can convert wav file to desired format with sox.

I'm sorry, but any attemp to play file with ossplay results in complete 
system hang with error:
unable to handle NULL ponter dereference at address 
0000000000000008.....(hang, no more output).
I tried many wav formats. So I can't get error log or period and buffer 
sizes, sorry.

Can anyone confirm to reproduce Oops with OSS apps (ossplay)?

I'm wondering whether this has anything to do with the capture.
Can you record the sound, and change the capture mixer element properly?


thanks,

Takashi

Just run arecord to record something.  And, change the recording
source via mixer.

So far, I got little report about recording, and I'm not sure whether
it works at all.

Should I change source WHILE recording or AFTER recording? Should I 
change it to OSS or just to another ALSA source?

I tried arecord with several sources and formats. I don't have mic or 
other recording device so the file is silent (and only 1 second length, 
I terminated arecord after 5 or so seconds, I don't know is 1s length is 
ok or not in this case), but at least it doesn't crash. Using ossrecord 
leads to NULL pointer dereference at 0000000000000008 and hang.

I just tested ossplay and arecord.
For me both result in a spontanous crash back to BIOS without leaving 
any traces in the log files.
Everything else works fine so far.

Seems that only one application at a time can use alsa. All other apps 
say they can't initialize sound until I close the first app.

Yes, it's a design, so far.
Right now, DSP is bypassed and the SRC is directly connected (as far
as I understood from the code).  So, I guess multi-playing won't work
without DSP codes.

You can use dmix instead.  At least, there is one positive report :)
For testing, just run like
	% aplay -Dplug:dmix foo.wav

OK, then the problem is consistent.
It's a bit tough to check without a proper log.
How about running with strace?  What is the last syscall before the
dead end?

I just noticed I still had a dsnoop/dmix set up and renamed asound.conf 
for retesting.
Now at least arecord doesn't crash the system anymore, but it only 
returns silence (Despite a mic being connected).

ossplay still crashes though and strace isn't of much use.
Running ossplay causes a sys reset so fast the strace output cannot even 
be flushed to disk anymore, neverless be up long enough to read it on 
the screen.

A serial console may help you there, assuming you have two machines.

Good idea :)

Just tried it, but even a 115200 baud serial connection isn't fast 
enough to give me more than the first three lines of useless strace 
output before it's back to BIOS.

Same here, not with serial, not with ssh, not even with a Camera
recording the screen....

No logs either...

By the way,
-amarok with xine as backand using ALSA works
-Flash movies with sound in Opera work
-Xine works flawless (nice sound)...just watched "Big_bug_bunny_080p stereo.ogg"

Now I am listening to my favourite song Diana_Krall_-_Black_Crow.mp3
(256kbps 44100Hz) with xine.
Clear, distortionfree, lovely sound!

I checked mplayer. It uses period size 1024 instead of 4096 and 16384 
buffer size (default). Sound is choppy (sound pauses is more frequent 
when rate is lower).
However an attempt to play the same file with the same period and buffer 
sizes with aplay results in complete system hang.

OK, that looks like a problem.  Looks like the timer resolution can be
short like that, or something racy in the timer handling.

Can you check whether this happens with XXX_SYSTEM_TIMER, too?

Or, does the patch below avoid the problem, at least?

After patch:

Without system timer:

aplay --period-size=1024 96000_16_Stereo.wav
Plays fine

aplay --period-size=1024 22050_16_Mono.wav
BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
Hang

With system timer:

aplay --period-size=1024 96000_16_Stereo.wav
Superglitch. Each sample is played many times before advancing to next one.

aplay --period-size=1024 22050_16_Mono.wav
Instant reboot.

Just to be sure: you don't enable XXX_CONT_RATE, right?
It's known to be buggy, so disabled as default now.

Please elaborate?  You mean 22.5k still doesn't work with the patch?
Does 22.5kHz ever work with other parameters?  It'd be really helpful
if you get the full Oops log...

The patch affects only the emu20k1 timer.  The system timer stuff
isn't touched by it.

The reboot implies that it's unlikely the timer but the driver wrote
something wrong (unless you have the set up that the kernel traps and
automatically reboot).  But, it's nothing but a wild guess at this
point.

Anyway, I updated the driver code a bit again.  Please check the
latest one.


thanks,

Takashi

Only 96000Hz stereo works here as of 15 minutes ago. Following .asoundrc
stanzas result in a hardware fault and return to BIOS:

pcm.xfi-dmix {
    type dmix
    ipc_key 1024
    slave {
        pcm "hw:2,0"
        rate 96000
    }
}

pcm.xfi0 {
    type plug
    slave.pcm "xfi-dmix"
}

pcm.default pcm.xfi0

Unfortunately, nothing was left in /var/log/kern.log.

The latest change in the timer code really broke playback for me.
Sound now stutters every 2 seconds.
It seems to go back to normal when I put back the TIMR_IP flag that was 
commented out in that patch.

Oh, thanks for noticing it.  I took the bit back now.
Looks like the bit is different from what I expected...

Interesting.  Is it a timer resolution issue, or loop size limitation?

By the way, the frontpannel headphone does not work.
Is it supposed to work?

(I Have this frontpannel but actually no X-RAM version of the X-Fi

I opened the external box for checking what's in there and noticed the 
headphone jack seems to have it's own dedicated second DAC (CS4392KZ), 
and audio interface receiver (CS8415A), so it could get a bit more 
complicated.
I'll see if I can find out more about that.

Also I found the GPIO flags that switch the relais, but that's probably 
useless as long as their function is not known. (It's 0x04, 0x40, 0x200 
and 0x1000).

The relays are for padding.
I.e. They switch in some attenuation for the mic or line inputs.

Re: Backported sbxfi driver (UNTESTED!)

With the latest drivers I have random stutterings. I can't say if they
occure regular, but they occure often. Sometimes every ~5 seconds,
sometimes with more time between, somtimes less...

mplayer --->
Öffne Audiodecoder: [mp3lib] MPEG layer-2, layer-3
AUDIO: 48000 Hz, 2 ch, s16le, 160.0 kbit/10.42% (ratio: 20000->192000)
Ausgewählter Audiocodec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)

Master and PCM channels are working.

Is it a regression?  I mean, did it ever work better than the latest
version?

Do you see the problem except for MPlayer?

Does the patch change the behavior?

No problems when using xine as backend or xine allone.

No, mplayer (using the smplayr GUI) behaves like I reportetd, xine
works like bevor.

Just one thing changed:
Running the same file with "mplayer file.avi" instead of "smplayer
file.avi" now results in a crase.
Without the patch I could at least run "mplayer file.avi" Now the
system freezes or just restarts.
No way to get mot info.

I'll revert the patch and check again.

Mhh, I reverted the patch but mplayer still keeps freezing my system now...
smplayer still works (with the stuttering) xine works fine.

Hi,

There is a "Q" missing from the end of  SBXFI_TIMER_FRE in 
/alsa-kernel/pci/sbxfi/sbxfi.c

aplay works 48khz and 96khz, sounds perfect.

Takashi, I'd like to help testing if I can.
Have a serial cable setup to capture console oopses.
And it does crash whenever it sees alsa/pulse audio.

It'd be great if you can capture the whole Oops log.
That was entirely missing for all the time.

Oops attached.

Caused when trying to use mplayer to play a wav that aplay played perfectly.

Happy to try anything to help.

Thanks, Jason

Did you capture the Oops via a serial cabel?
I had one attached too, but I never could capture an output... either
the system rebooted or died without a message on the serial console...

Anything special you did to capture the oops?

Kind regards
Bjoern

Yes, just a simple serial cable, no handshaking lines.
Just added "console=ttyS0,57600n8 3" to the command line to stop enable 
the console and stop X
I set the bitrate to 57600 to make things a bit faster.
Using CuteCom to capture the output.
Not had any instant reboots yet on the Intel based machine I am now 
using to test.
On my dual Opteron machine it does reboot, I doubt there is enough time 
to squirt out an oops.

What is the last kernel message from sbxfi driver?
Usually it prints some messages (as debug=1 as default).

Hmm... connection refused?  So it doesn't hang up at this moment yet.

The Oops shows somewhere in the hrtimer handler, so basically it's
irrelevant from sbxfi itself.  A possibility is that the driver made
some memory corruption.  Then it's a bit tough to catch.

Anyway, could you try the patch below?

And, if it's reproducible (just try mplayer first without aplay),
then you can add printk()'s and delays in each PCM callback to see
where this happens, for example.


thanks,

Takashi

I applied the patch and when trying "mplayer wn.wav" I consistently get 
the following message on the console

PANIC: double fault, gdt at c13f6000 [255 bytes]

nothing else, either reboots instantly or locks up.

In case you might find it of use I modprobed at debug=3 and ran dmesg 
before I ran mplayer. Output attached.

Sorry, I might be doing something wrong!

Your patch applies cleanly but build fails on emu10k1.
./configure --with-cards=sbxfi still get error...

My bad.  The patch for emu10k1 in alsa-driver tree must be updated, too.
Will fix now.

Fixed and uploaded now.
It might take some time until the changes are sync'ed.

Thanks, downloaded, patched fine.
Attached dmesg_modprobe.txt shows output before playing anything.

No sound now using  the oss workaround "echo mplayer 0 0 direct > 
/proc/asound/card0/pcm0p/oss"
Mplayer starts but doesn't increment shows 0% 0seconds etc etc, it can 
be interrupted ctrl-c, the PC remains functional, just no sound.
dmesg_after.txt is the tail end of dmesg after interrupting mplayer, I 
trimmed it as the first couple seven lines repeat for about 330K in the 
original log :)
Instant reboot when trying mplayer without the oss workaround.

aplay -Dplug:dmix:0 wn.wav still works.
Trying mplayer after aplay freezes the machine with no output onto the 
console.

Thanks again, Jason

OK, so the patch doesn't help, and it brings another problem.
What about debug=2?  This will give much less log, I guess.

Even with OSS proc hack?

debug=2 is still too big to see the start of playback.
If I can get the buffer big enough to find the beginning I'll post it :)

Yes, if I aplay first it locks up entirely when I issue OSS proc hack 
then run mplayer.
Without running aplay I can get a dmesg but mplayer makes no sound.
I've put the debug=1 output along with the commands etc below.

That'll be good.

Just to be sure: is it the driver with my patch or without the patch?
The patch seems broken anyway, so abandon it, and check only without
the patch from now on.

Have reverted to unpatched version, now logging kernel messages to a file.
The attached is the output for debug=2 from running the mplayer with the 
oss proc fix.
WARNING... the gzip expands to 4.5MB, which explains the overflow on the 
dmesg ring buffer.
But only the first hundred lines and last ten are different, the rest 
are all the same as far as I could see.

The only things I noticed that does change is that the repeated lines 
start like this :-

Oct 23 20:45:28 sentry kernel: SBXFI: IRQ = 
0x500

Oct 23 20:45:28 sentry kernel: SBXFI: POINTER = 0x3e0

And that the pattern changes after a short time dropping one of the 
POINTER lines.
Screen output below to show commands used.

So the stream is started at the state where the TLB is cleared.
The fix patch is below (and I already committed it).

Author: Takashi Iwai <tiwai@suse.de>
Date:   Fri Oct 24 10:35:03 2008 +0200

    sbxfi - Fix multiple hw_params calls
    
    The last change seems breaking the case of multiple hw_params calls.
    Although the TLB is cleared unconditionally beforehand, it's not
    re-asssigned because snd_pcm_lib_malloc_pages() returns 0.
    Now, call sbxfi_setup_tlb() unconditionally, too.

Yes that has fixed it.
Tested with mplayer (still needs oss proc fix) and aplay. Both sounded fine.

Thanks for quick checking.

So, the mplayer problem still exists - supposedly the same symptom?
I'll take a look at OSS emulation code later.

Yes, mplayer without the proc oss fix gives an instant reboots with 
nothing on the console.

Thank you for your heroic work without any xfi hardware!

Re: Backported sbxfi driver, possible fix

[Thomas Scheunemann]

I think I found a bug in the driver, which at least for me was
responsible for the crashes with pulseaudio.

A little backstory:

I have a Fedora 8 System with an SB X-Fi installed and of course
no sound. I didn't want to replace the entire ALSA driver, so I
just took the files sbxfi.c and emu20k1-regs.h from the unstable
sources, wrote a small spec-file and am now at a point where I
can just "rpm -i" the driver as a dkms package and just modprobe
the driver.

After that "speaker-test -D hw -c 2 -r 96000 -t sine" works just
fine, but as soon as pulseaudio is started my System froze.

The bug I think I found is in the get_xfi_order function. As long
as pages actually is a power of two it works correctly. But if
pages isn't a power of two it should round up, but it rounds down.
As a result I believe this screws up sbxfi_alloc_tlb_pages.

After a small modification to get_xfi_order:

 		order++;

 	return order;
 }
 
the driver started working with pulseaudio, it doesn't crash, and I
even get sound though it still is a bit distorted.

Thanks for the patch.
Yeah, I found the very same problem in this morning, but I couldn't
update the repo and snapshot until now due to the server crash.

My solution is to use roundup_pow_of_two() instead of the own
funciton.  This should work better in general.

Anyway, I updated the repo (and rebased, sorry), updated the snapshot,
too.

thanks,

Takashi

I certainly agree that it is better to use an already defined function
instead of reinventing the wheel.

But this new version causes an immediate reboot on my machine even with
the previously working speaker-test. If I interpret linux/log2.h correctly
the desired function should be order_base_2 instead of roundup_pow_of_two.
At least it works for me after that exchange.

Oh my.  You're right, it must be order_base_2(), of course.
I was too hurry to fix a bug after the server crash :)

Now fixed and updated.  Thanks!

Latest unstable (25Oct 19:57) works from command line with mplayer, 
without the proc oss fix.
aplay still works but only with dmix.
Now also almost working in gnome with pulse, sound is recognisable but 
with lots of interference/corruption.
Machine did not crash at any point!

This was running on 2.6.26... is this a problem? SUPPORTED_KERNELS says 
2.6.25 or earlier?

Confirmed.
The stuttering got better, but is still present.

Xine works flawless.

All other common samplingrates work flawless. Could someone confirm that?

Just using "aplay file.wav"

More noticable ist it when using mplayer. Crackles a lot with 8000Hz and 11025Hz
"mplayer file.wav"

mmh, xine crackles too. Please someone confirm, otherwise the files may be bad.

Thanks for you awesome work!

By the way, what's next on your plan when stereo output and recording
is working flawless?

Tried the latest driver.
All is fine (haven't tested recording however) except pulseaudio 
(doesn't work) and wine (sound is mega-glitchy, possibly because of 
strange period and buffer sizes it uses: period=544, buffer=8704). 
System is stable. OSS works fine.

Maybe due to the sample rate?  I guess with 48kHz it would be a more
sane period/buffer size.

With that option pulseaudio works better (still some glitches, but very 
small). But wine still corrupts sound.

--small). But wine still corrupts sound.

Hmmm....after sound got currupted, I started playing a file with xmms. 
Sound was horrible, but I couldn't get hw_params, because the contents 
of that file are 'closed'! How can this be if xmms uses alsa at that time??

Hmmm.. Looks like it is not dmix fault. wine requested something of
driver that caused all sound to be glitchy until driver is reloaded.
dmesg output with debug=3 is attached.

Ok, got pulseaudio to work, but it causes the same problem - sound 
becomes mega glitchy everywhere. So looks like even if driver doesn't 
crash the system, playback is still unstable and can become glitchy. 
Also I can not make Fedora 9 to load snd-sbxfi automatically. It ignores 
modprobe.conf and pulseudio does not detect snd-sbxfi as driver for my card.

Hm.  The probme like stuttering is a bit hard to analyze.
In most cases, it comes from the inaccurate PCM hwptr (i.e. the value
calculated in PCM pointer callback is wrong), but not always like
that.

To be sure - this symptom is only on sbxfi, right?

I'm not sure whether this is really related with sbxfi.
For checking that, you can load snd-dummy driver instead, and run
smplayer with it.

A few important features are in my mind:
- continuous rate support
- multi-channel playback
- multi-stream playback

Not sure whether I can achieve any of them without a document,
though.

Do I understand correctly that the card internally resamples the sound 
to a different rate using the zero-order-hold method? If so, I'd rather 
not see this feature at all unless the "i_want_horrible_sound" parameter 
is passed, because software can do it better, and some program will 
surely default to using this hardware misfeature.

OTOH, Wine is doing this for ages and nobody except me complains

Wine causes sound corruption with this driver for me (along with some 
other software like Pulseaudio).

Does it happen also with base_rate=48000 option?

It'd be helpful if someone can summarize the working and non-working
cases.  For example,

global info:
1. sbxfi driver version (date & HEADs)
2. base_rate value
3. system details (x86-64, distro, kernel version, etc)

for each app:
A. Application name / version
B. working or not-working, problem descriptions
C. ALSA or OSS (you can see it in /proc/asound/card*/pcm0/sub0/hw_params)
D. period_size and buffer_size (ditto, or in kernel message)
E. any special options

Maybe also nice on Wiki...


thanks,

Takashi

Add prefix numbers (1, 2, 3) to each item.

See HEAD files in alsa-driver*/ and alsa-driver*/alsa-kernel, and take
the first line.

So one wired thing:
I first tested mplayer... all samplingrates except 3200, 48000 and
96000 were bad.
Then I tested xine... everything was bad.
Then I tested mplayer again to dump the info into the files (bug-mplayer)
suddenly all samplerates were fine.... testing again and all went bad again?
But basically you can say everything is crapy right now.

Kind regards

Forgot to ask: which SBXFI model?  The product name, PCI ID, PCI SSID,
and /proc/asound/cards entry please.


> 2. base_rate value

What about base_rate=48000?

BTW, I changed now base_rate to 48000 for testing as I got more
positive results with it.

What if you do the following (as root)?

	# echo "mplayer 0 0 direct" > /proc/asound/card0/pcm0p/oss
	
This will disable the conversion in OSS emulation, so mplayer will
take 96kHz as is.

Not sure about this...

As a module parameter, either in somewhere modprobe.conf or such, or
via modprobe command line option.

I changed the latest version to use 48k as default, so you can just
grab the latest snapshot, too.

Weird.  What happens if you force to the sample rate to 48000 via
mplayer's option?

First the good news:
mplayer does play all samplerates very clear! Pure, lovely sinus ;-)
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 48000 (48000/1)

OSS format: S16_LE
OSS channels: 2
OSS rate: 48000
OSS period bytes: 4096
OSS periods: 16
OSS period frames: 1024


Now the bad:

Xine does not work... crackles horrible on all sample rates when run from cmd:

mmh, I recompiled xine-lib without mmap support but I still get
access: MMAP_INTERLEAVED

could mmap be a problem?

Maybe it's accessed via alsa-plugin.  What about let xine using
"hw" PCM device instead of "default"?  Then xine would play at 48kHz
natively without conversions in alsa-lib.

Possible, can't determine exactly at this moment...

mmh weird... xine works...
Couldn't reproduce my previous report... thought I changed nothing...
Please ignore the xine crackeling... seems not reproducable (If I can
reproduce it, I'll let you know).

Likely it's a wrong guess.  emu20k1 has the following register bits.

# define SRCCTL_PITCH_ROM	(3<<11)	/* pitch ROM select */
#  define SRCCTL_PITCH_HIGH	(0<<11)	/* 0 to 8.0: very high quality */
#  define SRCCTL_PITCH_EXT_HIGH	(1<<11)	/* 0.26 to 1.72: extermely high qual.*/
#  define SRCCTL_PITCH_88kHZ	(2<<11)	/* 1.8375: 88.2kHz 48kHz */
#  define SRCCTL_PITCH_96KHZ	(3<<11) /* 2.0: 96kHz 48kHz */

Alex,

I added that comment (takashi cut and pasted my text). No resampling is
done.
Say you have a buffer that is running at 48kHz.
So you have say 480 samples at the 48kHz rate.
But if you want to transfer 44.1kHz rate samples over it, you only want
441 samples to be there, so what to do with the left over 39 samples.
What the xfi does is next to each sample it adds a "valid" tag.
So, the xfi adds those 39 samples but marks them as "invalid".
The xfi then drops the 39 "invalid" samples, leaving only the 441
"valid" samples just before sending them at 44.1kHz to the DAC.
Does this explain things a bit better.
FYI, the xfi actually works internally at 384kHz, so it is actually
marking a lot of samples as "invalid".

Kind Regards

James

Hm, so what is special about using 44.1kHz if many samples in the
audio-ring are already marked as invalid even with 48kHz?

It'd be helpful if you could provide a bit more information (or a
pseudo-code) for supporting non-48/96kHz samples.

James,

Thanks a lot for the info. Does it mean that the core runs at 384kHz, 
while codes are clocked by another clock signal PLL'd from the master 
clock to the required frequency? Theoretically this could allow running 
different outputs/channels at diferrent sample rates :)

Pavel.

Do you have no sound quality problem with dmix like other people?

What about base_rate=48000 option?

Heh, finally.

You can ignore what stated in SUPPORTED_KERNELS.
It's just an excuse not to support vendor kernels.  Distro vendor
kernels are often way too modified to support properly by the
out-of-tree driver.

FWIW, the current alsa-driver (and unstable) snapshot should work fine
with up to 2.6.28-rc1 kernel.  sbxfi is marked to be available on
2.6.25 or later kernels.  It won't be built for earlier kernels.

No dmix trouble when I run "aplay -Dplug:dmix:0 wn.wav" produces perfect 
sound. Wav is three minutes long and it was 100% ok throughout.

Genius! It is now working through pulse PERFECTLY.
Have two instances of mplayer playing right this second.
Can hear both tracks playing without any trouble.

I just edited one line in /etc/pulse/daemon.conf not sure it is the 
option you were talking about above but it works for me!

Will put the card into my 64bit main machine in a minute and try it there :)

One another thing I'm wondering is whether this happens only with
OSS.  What happens if you do like the following to disable the sample
rate conversion?

	# echo mplayer 0 0 direct > /proc/asound/card0/pcm0p/oss

Bah, then this sounds like a bug in OSS emulation code?
Hmmm, now need to dig into that old crap...

Running mplayer freezes the PC every time.
strace  confirms it is always at the same point.
