Well, since OSS is officially broken for USB recording, here we go with ALSA:
I can't record anything using the microphone which is integrated into my USB webcam. The cam shows up as a device (alsamixer -c 1), and I can adjust the only available mixer which is for <Mic> in [Capture]. It's not muted and it's maxed out.

You might notice the device comes up as [default] instead of having a proper name. If I run...
$ arecord -Dplughw:1,0 -f cd -vv /dev/null
or
$ arecord -Ddefault -f cd -vv /dev/null
then it out puts a lot of stuff (both the same) which I pasted below, but at the bottom it doesn't show any #'s and %'s to indicate the volume. The blue light on the webcam also turns on. If I save to a file instead of /dev/null and aplay it, it's just silence. Here's the output from the above command:
[lucullus@schatzkiste ~]$ arecord -Dplughw:1,0 -f cd -vv /dev/null

Although if I run
$ arecord -Dhw:1,0 -f cd -vv /dev/null
then it fails with:
Recording WAVE '/dev/null' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
arecord: set_params:984: Channels count non available"
I made a screenshot illustrating that everything is turned up and unmuted:
And here's the test.wav I recorded with arecord. It's actually very short, no matter how long I record:
http://omploader.org/vMXZ5MQ
Alread tried:
- Switching the two devices so that 0 becomes the webcam and 1 the intel-hda through modprobe.conf but that had no other effect other than the switching.
- Playing a lot with the device, muting, triplechecking volumes etc. etc.
- Trying recording something in audacity. First time, the light goes on but it doesn't record, on subsequent tries, audacity spits an error stating "error opening sound device".
- Trying it in linphone, light turns on, but other party can't hear anything.
- Adding pulseaudio, but this had no influence of course.
Any ideas how to fix hits? Btw, it used to work in ubuntu 9.04 for some reason. Tried the mic on two Archlinux boxes here, it's exactly the same on both. But everything works, everything is very up to date (I'm sure ubuntu has older versions of stuff). Also, in the beginning I was still running 1.0.19 with kernel 2.6.29, instead of 1.0.20 with 2.6.30, so I think it must have happened before that. I guess that it's a regression in the kernel or driver or something. Well, all the info is in the alsa-info link above. Hope I can work this out!
Thanks for any input!
Regards.
