Hi,

Here's my setup and what's currently working.

Enemy Territory Quake Wars worked but crashed after a couple of minutes. 
Graphics card is new so can't be sure what happened.

If I set Gnome to use OSS I can get sound from Rhythmbox.


Sorry to tag this on to the end of this message, the problems below are 
likely of my own causing rather than the sbxfi driver...

I'm investigating why when I select alsa or pulse in Gnome I get an 
error on clicking the test button.
"audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! 
gconfaudiosink: Could not open audio device for playback."
Selecting OSS and clicking test I hear the sine wave.
But I cannot hear any desktop effect noises or the system bell.
Same issue with KDE. I hear the log on tune but nothing else from the 
desktop itself.
Possibly my machine is just too messed up and needs a re-install, it's 
been upgraded continuously from around FC3 and could do with an overhaul.

Regards, Jason

You can't hear desktop sounds because they always use pulseaudio no 
matter what sound system you select as default. For me pulseaudio plays 
first sound fine after start, others are corrupt along with sound from 
all other apps. I'll post hw_params later. Also pulseaudio tends to 
crash often with this driver so I suppose your problem is the same.

Can confirm that once pulse (on FC9 at least) gets involved it sounds 
terrible.

I worked out that I had removed a package pulseaudio-esound-compat at 
some point in the past and never realised that it contains the symlinks 
that gets Gnome to start the pulse server.
Once that was fixed the desktop effects started working but only out of 
my USB headset... and nothing I can find in the gui lets me do anything 
about it.

mplayer and firefox/flash sound terrible, very tinny and scratchy.
This is with the base_rate=48000 option set in modprobe.conf

Thanks, Jason

In many cases, the pulse problem comes from the in accurate DMA position
calculation.  PA is often too aggressively updating buffers.

Do you mean a regression with 48kHz in comparison with 96kHz?

Thanks, I knew there was a reason I stripped pulse out of this machine 
when I installed FC9.
Is that a bug in pulse or is it something that will improve with the 
sbxfi driver?

Sorry that was a bit ambiguous, I'd never tried 96kHz.
Have just changed base_rate to 96kHz and it performs identically to 48kHz.
Pulse mangles the sound in just the same manner at 48kHz or 96kHz.

While I was poking about in my alsa configuration I noticed that there 
is no /etc/alsa/cards/SBXFi.conf
I think pulse looks for it, get errors shown after running pulseaudio -vv
ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 
'cards.SBXFi.pcm.surround51.0:CARD=0'  
Would that make any difference to anything?
(Sorry if pulse issues are totally off-topic)

Basically it's a bug of the driver.

Ah, so you meant mplayer/flash with PA backend?

It just tries to non-existing configuration, and you can ignore it.

Yes.
I also tried mplayer using -ao=alsa or -ao=oss and the sound is still 
corrupted, even after killing the pulse daemon.

If I get the chance I will put the card into a 32bit machine tomorrow 
and see how it sounds there.

Thanks, Jason

The sound once corrupted will remain so until driver is restarted.

Ok, looks like with the latest snapshot (28.10.2008 15:19:00) pulseaudio 
works fine. But wine not. The bad thing is I can't get hw_params 
somehow. When pulseaudio is started hw_params always say 'closed' even 
if sound is played at this moment. I'll try to remove pulseaudio and 
test wine again.

Well, I wasn't lucky. Even without pulseaudio hw_params are 'closed'

Ok, was able to get hw_params:
access: MMAP_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 48000 (48000/1)
period_size: 1088
buffer_size: 4352

Why so weird values?

Maybe related with the default sample rate 44.1kHz?  Who knows...

Does the patch below have any influence?
This restricts the period/buffer size aligned to 1024 bytes.
Also, it may fix the PCM pointer calculation somehow.

It's ridiculous.  Does PA really access the right device (i.e. X-fi)?

With the latest unstable I grabbed this afternoon everything is sounding
pretty good right now!

pulseaudio is now working.

[jason@quad alsa-kernel]$ cat HEAD
2f280189c7779e0efbeead8eb03b179d141dd196 Merge commit 'stable/master'

I can get hw_params when there is something playing.

cat /proc/asound/card0/pcm0p/sub0/hw_params

access: MMAP_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 96000 (96000/1)
period_size: 2048
buffer_size: 16384

Can't get mplayer to play at the same time as flash in firefox but I
don't really know if I've ever managed to do that under pulse...

Thank you again Takashi,

Jason

Hmm... I haven't changed sbxfi code since yesterday.
The last change was:
   commit 941ec54e47f635f63621d3852253d9ef9b11132f
   Author: Takashi Iwai <tiwai@suse.de>
   Date:   Tue Oct 28 08:00:24 2008 +0100

      sbxfi - Use 48kHz as default

Though, I'm glad to hear that it's working, of course :)

Or, did you apply my last patch I posted?

The flash with PA can work with libflashsupport.
It'd be better to use it with flash-10, though.

Patch doesn't help. Though it really makes period and buffer to be 
aligned to 1024.
I have discovered however that sound only gets corrupted if wine tries 
to use alsa directly.
If it uses pulseaudio (it's eSound emulation), sound is fine. Other apps 
(including MPlayer) with pulseaudio work just fine.
dmesg output with debug=2 for the case when wine uses alsa directly is 
attached.

Ah... a little version confusion here...

This morning I downloaded unstable again and tried the patch.
It wasn't working, garbled sound through pulseaudio as previously mentioned.
I worked out my pulse installation was missing a few packages (Fedora 
folk why aren't all pulse related packages named pulse-* ?)
Not sure what changed but once all the pulse pieces were in place and I 
had locked the default device to the sbxfi it all sounded great.
That was without the patch.

Just applied the patch again and everything still works.

Thank you, I had grabbed flash 10 a couple of days ago as I tried to get 
it all going.
Although it was making nice sounds it turns out it was not using pulse.
Now I have the volume control installed I can see what is going on...
Cured flash by installing libflashsupport.i386
libflashsupport.x86_64 package doesn't really help with adobe's i386 
flash. Doh.
