snd-usb endpoint rework

snd-usb endpoint rework

[Aurélien Leblond]

Hello everyone,

I compiled today the Kernel 3.4.0-rc7 from the git and used this git
to add the FTU support:
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git

Unfortunately, all my USB sound card simply stopped working.

The FTU doesn't produce any sound, nor through Alsa or Jack.
I tried playing a simple song through mplayer and nothing. I double
checked the mixer, all volumes are set as they should.
I checked dmesg, no error that could help.
I'm running Ubuntu, and the only thing I can hear is the welcoming
sound of ubuntu being cut-off almost instantly.

I tested my Edirol UA-25Ex, it is working all ok.

Let me know if there is any other info I could provide that would help,

Thanks in advance,
Aurélien

Correction, the UA-25Ex doesn't work either.
The sound dies out after a few minutes being used.

When the sound dies out, dmesg prints:

[  550.114621] urb status -32
[  551.601237] urb status -32

Odd. I did just that - built a kernel from Takashi's master branch - and
cannot reproduce the effect you're seeing. I'm testing with both the FTU
and a NI Traktor Audio 6 (which is a class compliant device) and both
stream reliable.

Are you totally sure that your hardware setup is ok? Did you change the
USB cables or anything? Does running an older kernel, while leaving
everthing else the same, solve the problem?

Can you provide more context of the logs?

Yes, I checked running the standard Ubuntu Kernel, and the FTU/UA25-Ex
are running ok.
But it is a 3.2 Kernel, so the stream logic is not available.

Yesterday, I compiled alsa-driver from the alsa-driver.git and
alsa-kmirror.git (I'm actually not sure what is the difference between
this gits and the one from Takashi) and installed it on the kernel 3.2
coming with Ubuntu.
I get the exact same results:
- the FTU doesn't produce any sound BUT the Ubuntu welcome one.
Although the mixers are ok, I'm starting to wonder if they might still
be muted.
(on that note, the "internal" sound of the FTU is ok, I can play my
guitar plugged on the soundcard and hear it properly).
- I haven't tested the UA-25Ex with that setup, I'll try that this evening.

Can you try using something like xmms maybe? I'm interested whether the
audio interface does consume any data or if the whole thing is stuck.

There were some other patches to augment the mixer routing
possibilities. Not sure if that has any relation to your issues, but I
doubt it.

That doesn't include any streaming to the host and back, so that doesn't
help much unfortunately.

Please do and also include the lines that are produced when you plug in
the device.

Felix, Grant - can you try booting a kernel built from Takashi's master
branch and check with the FTU and other cards?

This is now getting weirder and weirder, but here are the results of
today's testing.

Yesterday and today, I have been running the Kernel 3.2.16 with the Alsa git.
Yesterday I couldn't play any sound whatsoever with the FTU, and the
UA25-Ex was dying out after a few minutes.

Today:
(the testing is done using VLC connecting directly to ALSA, I removed
pulseaudio from Ubuntu a few days ago to eliminate that as a possible
cause)
The first time I started my laptop with the FTU plugged - no sound,
VLC is not hanging (I can see playing time move along).
Unplugged the FTU, plugged back - VLC is now playing sound, but the
sound quality is very "low-def" (I'm not sure how to explain that
properly).
Restarting my laptop, FTU plugged in - VLC is now playins sound, still
with very poor sound quality.

Restarting my laptop with the UA-25Ex plugged in - VLC is working ok,
sound quality is good, been running it for 10 minutes without a
problem.

Im both cases, starting Jack results in an immediate freeze of my
laptop with CPU going 100% (I guess, as the laptop fan is going
crazy), and I guess it is related as running Jack on the previous
driver/original Ubuntu kernel is ok.

I cannot reproduce this problem anymore. If I encounter it again, I'll
save a trace of the dmesg.

It's quite hard to provide you with proper info as it almost looks
like everyday produce a new scenario.

If there is anything I can provide to help, let me know,

I think I ran into the same thing today. The reason for me was that the
new mixer controls that were added now allow setting the effect unit.
Actually, if you hear what I heared, this is just a simple reverb effect
that is overlayed. And yes, it sounds cheap :) I ran "alsamixer
-Dhw:Ultra" and switched all related controls off, and the the sound
came back again as expected.

Might be the controls are not yet properly initialized, and the hardware
comes up in an undefined state. That would be easy to solve.

That is another issue then, but certainly something I need to look into.

Usually the reason for loosing the overview is too many factors that are
involved when testing. Try to minimize the things you change from one
test run to the other as much as possible, and test extensively with one
configuration.

Every bit and piece of empiric information is valuable and might help
finding the issue :)


Thanks for your help,

Re: snd-usb endpoint rework

Hello Daniel,

Here are the results of today's testing.
I don't know if they'll help in anyway, but here we go.


BOOT WITH THE UA-25EX

Trying to use aplay:

blablack@igorito:~$ aplay 10\ -\ Track\ 10-L.wav
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'

aplay: main:682: audio open error: No such file or directory

blablack@igorito:~$ aplay -D default:CARD=UA25EX 10\ -\ Track\ 10-L.wav

Second one work ok... Let it play for several minutes and it's all fine.


BOOT WITH THE FTU

aplay: main:682: audio open error: No such file or directory

blablack@igorito:~$ aplay -D default:CARD=Ultra 10\ -\ Track\ 10-L.wav

No sound...
I tried to reboot several times, unplug/replug, checked alsamixer: all
look fine to me but still no sound.
Actually, it is not "exactly" no sound: I can see the 4 front leds
flash very quickly, and I can hear a click in the speakers (with the
FX, the click is longer due to the reverb, handy to notice it!).

Using mplayer...well I don't know if I'm just an idiot or if there is
a deeper problem, but I can't get the alsa parameter to connect to the
sound card. And if I don't specify the -ao parameter, I get the same
error as aplay "cannot find card 0".

Using VLC, I can see that VLC doesn't get stuck but plays something,
unfortunately, still no sound.


In dmesg, I get:
[    3.031270] usb 2-1.2: new high-speed USB device number 3 using ehci_hcd
[    3.118175] usb 2-1.2: config 1 interface 3 altsetting 0 bulk

[   18.109496] ALSA mixer.c:796 usb-audio: set quirks for FTU Effect
Feedback/Volume

The first error message is "ok" I far as I remember, and the second
message shows the detection of the FTU - all look fine to me...



IN BOTH CASES, FTU AND UA-25EX

Starting jack result in an immediate freeze of the system.


If there is anything else I can provide to you, let me know.
Hope all this help somehow!

Re: snd-usb endpoint rework

[Felix Homann]

Sorry, I can't help testing at the moment. I'm extremely busy preparing a
couple of shows I'll be playing in the next few weeks.

But Aurélien's problems remind me of an issue I had some weeks ago. The
issue was caused by a jackd process that was unintentionally launched via
D-Bus on start up.

Thanks! Which version of your kernel is this? The one with the new driver?

What does "aplay -l" show? Also, what does it show on the older Ubuntu
kernel? Is there any difference?

The 4 front LEDs on the FTU signal input level activity, not output. Is
there anything connected to those inputs?

I really fail to see any of these issues on my system. I tried with both
jackd and jackd2 and set them to real time priorities and chose 64 bytes
sample frames in PureData. All good, no lockups. Can you describe your
jackd setup? How do you start it?

I need to be able to see the issues you describe. Once I do, I'll work
fixing them!

ok I just built a new kernel.

I started with 3.4 then applied the rt7 patches then merged the topic/misc
tree from sound (to get the ftu fixes from felix and daniel

so I have 3.4-rt7+sound/topic/misc

checkout v3.4 tag then apply the -rt patches using quiltapply then merge
sound/topic/misc

This all seems to be working ok. if I start jack with anything less that
128 samples It starts but I get no audio and lots of xruns (this is the
same as on previous kernel 3.4-rc4-rt5)

i've run jack_iodelay through a loopback (TRS from output 3 to input 3 on
the back of the FTU) for several hours without any problems

Felix,

the effects controls are not obvious to me I thought there were independent
fx sends for each output so expected 16x4 new controls plus the returns but
maybe that's not howitis.

also has anyone looked at how metering is reported on the wire?

I have been confused about it, too. But that's just how the FTU works.
There are only 16 sends.

At least I have not.

Hi Daniel,

I have tried to do a bit more thorough testing, find the details below.

That is just me being an idiot. Ubuntu never mounts a USB sound card
on the first slot.
Compiling with the original Alsa coming from Ubuntu, I get the same error.

There are stuff plugged on the 3 first inputs (2 for my guitar, 1 for
my mic), bit they are all turned off during testing.
This click and the 4 leds flash is very similar to the one you have
when the FTU is plugged in to the USB port after being turned on.
Somehow, when I want to play something, it makes the 4 leds flash + a
click/crackle in the speakers.

I hope this will help you find out where the problem is.
At least for now I can use the 3.4.0 kernel with the UA-25Ex

Re: snd-usb endpoint rework

[Aurélien Leblond]

Hello Daniel,

As I told you in my previous mail, after few hours of frustration and
testing, I decided to do a fresh install of Ubuntu 12.04 64bit.

After reinstalling Ubuntu, my first step was to compile Takashi's kernel.
And it worked! I could play a song on the FTU, run Jackd, etc.

Unfortunately, after re-installing all my music software and updating
Ubuntu, I'm now back to the scenarios I presented to you previously...

What I will do now is:
- Keep the .deb of the different kernel I compiled.
- Re-install once again my laptop.
- Not do any update nor install anything but the kernels
- Do my testings.

If this works, I guess we can conclude that something in Ubuntu is
messing with the sound-usb modules.

I'll keep you updated.

If you have any updates, let me know,

Aurélien

Re: snd-usb endpoint rework

[Aurélien Leblond]

Hi Daniel,

After the last reinstalling my laptop one last time, I cannot
reproduce the issue anymore.
Kernel 3.2.16 from Ubuntu compile with the Alsa drivers from GIT and
Kernel 3.4 RC7. I have been playing music all day today without any
issues.

The 3 big differences I have compared to my previous install are:
- I used to have the RT_GROUP_SCHED option deactivated in my kernel to
be able to run jack with runtime. I don't seem to need it now in
Ubuntu 12.04.
- I used to install the Ubuntu Proposed Updates (those are untested
packages), I didn't this time for sake of stability.
- I used to use the kernel .config file from the Ubuntu LowLatency
kernel as my base. This time I used the .config of the generic kernel.

To be honest, now that my pc is working, I wouldn't change a thing :)
But if you would like me to test the 3 points above and to try and
find what the problem was in the first place, let me know,

Regards,
Aurélien
