Hi All.
I'm new to Archlinux and I have the following issue with my USB WebCam (Microsoft VX-1000) : I can't get no sound out of it.
Both the video and audio devices are detected and proper modules are loaded (gspca and snd-usb-audio).
Video works fine.
arecord -l give the following results :
**** List of CAPTURE Hardware Devices ****
card 0: CK8S [NVidia CK8S], device 0: Intel ICH [NVidia CK8S]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: CK8S [NVidia CK8S], device 1: Intel ICH - MIC ADC [NVidia CK8S - MIC ADC]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: camera [USB camera], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
which looks ok to me.
But when I tried to record something (arecord -D plughw:1,0 -d 5 test.wav) then play it back, I can't hear anything.
I even tried to cat /dev/dsp1 into a file then play it back with aplay. Nothing.
All this tests were run while in command line with no DE running (to prevent conflicts with ESD and the like).
After 5 hours of googling, I can't find any solution. Help me, pleeeaaaase.
Here are some more info, in case it might help :

Thank you very much in advance.

Before you pull your hair out, did you check the Microphone sound level in alsamixer? It might be muted.

I mic is unmuted, that was the first thing I checked. And I ran camE during the test to be sure that the webcam is on (green led on).
Another strange thing is, when I run alsamixer, I can only lower the mic capture volume, not raise it. Curious. It works ok in gnome-alsa-mixer though. I guess their might be an issue with the device's control interface, due to a problem with the alsa driver (my webcam not being supported yet).
I really can think of anything else.
Anybody has another idea... please... before I lose the rest of my hair...

First of all, USB Speaker? I didn't even know those existed. Not sure. You might want to go to Google Linux and look for information on your specific device. Or, someone else who has done something like this can help you out. Post it in hardware issues maybe.

Same problem, same Microsoft VX-1000.
But I also had to install latest gspca driver from http://linuxtv.org/hg/~jfrancois/gspca/ to get video working.
Did you solve your "no sound problem"?
