Hi,
This is the latest git kernel snapshot.
I've just bought a "Gembird EHS-USB" headset (this is with a microphone).
Audio playback is OK, but recording is not. Applications do not find the
"capture channel". E.g. alsamixer shows only the PCM channel, but when I try
to switch to "capture view", it quits with:
alsamixer: function snd_mixer_find_selem() failed: Invalid argument
lsusb -v (this will be long...):

In the dmesg output I could not see snd-usb-audio being loaded. Could you
check with lsmod if that module gets loaded, and modprobe it if it is not
loaded. Also, check if there is acapture device in /proc/asound/devices
for this "card".

Could you post the output of "amixer"?

Does something show up in the output of "arecord -l"?

Your device does not have any capture mixer elements.
Old versions of alsamixer had a bug that would cause it to crash like
above in this case.

This is AlsaMixer v1.0.9a.
Now I'm a bit confused. Do I have a problem at all? :)
If arecord seems to find it, but there is no mixer
for it, does this mean that the microphone is visible for alsa but no
recording level can be set for it?
Afternoon at home I have to experiment with it a little more..
Thanks,
Szekeres Istvan

the module is loaded and the playback is fine. Only recording is a problem..

Indeed. The microphone is really working. Now the only problem is that I
tried it under skype (that's why I bought the headset), and under skype it
is not working at all (strace revealed that skype is writing 0s to the sound
device) - so I'm afraid this problem is out of the scope of this mailing
list.
Other applications (e.g. gnomemeeting) are working correctly - both for
playback and recording through the microphone.
Thanks for the help anyways. At least now I know that the problem is not in
the headset.

Ok, after some experimenting the results are the following:
- Using latest git version of the kernel -> skype is not working
- Using 2.6.12.5 -> skype is working
- Other apps are working in both versions.
How can I investigate why does not skype working in case of the git version?
Thanks,
Szekeres Istvan

Does it read non-zero data?

It's important to know whether it's a problem of usb-audio or the OSS
emulation.
First, you can try aoss wrapper for the user-space OSS emulation.
Also, try "buggy-ptr" option for oss proc file (see
ALSA-Configuration.txt). This is a newly added option for the apps
which assume the broken implementation.

That's more interesting.
Can you get a stack trace via gdb?

I already tried aoss, the result is a big fat SIGSEGV.

I believe this has been fixed in ALSA CVS for weeks.

I have a stack trace but I think a patch for the solution is more useful ;-)

Next thing is to compare the kernel oss emulation with aoss on a non-working
kernel.

Yep, that's why I wrote to try 1.0.10rc2...

Oh apparently I didn't suggest it in this thread.
Anyway, it's already fixed on 1.0.10rc2.

Hello
Headset: Plantronics DSP 400 (047f:0ca1)
Distro: Ubuntu 8.04
output from tsalsa script (from #alsa) : http://nopaste.com/p/a8yymxldp
Problemdescription:
After some time(~0.5-1.5 hours) listening to music my headset suddenly
stops playing. If I try:
When the headset crashes dmesg says
ALSA /usr/src/modules/alsa-driver/usb/usbaudio.c:943: timeout: still 3
active urbs...
at the beginning the number of urbs were 4 but I blacklisted the usbhid
module (my headset has a volumecontrol) since then it hangs by 3.
/etc/init.d/alsa-utils stop cardid I get the message
"amixer: Mixer hw:1 load error: Invalid argument"
I also downloaded alsa-source (from the reposity)and built the
alsa-driver. Because
when I try sudo alsa force-unload or modprobe -r
modprobe hangs and I can't Terminate it.
When the headset crashes dmesg says
ALSA /usr/src/modules/alsa-driver/usb/usbaudio.c:943: timeout: still 3
active urbs...
at the beginning the number of urbs were 4 but I blacklisted the usbhid
module (my headset has a volumecontrol) since then it hangs by 3.
So the only thing what I can do is reboot to get it working again. It's
really annoying.
I first asked at #also for help but they couldn't help (except that it's
maybe somehow related to the usb subsystem) me but gave me the advice to
post my problem here.
Thanks
Anselm
