USB webcam microphone not working
Hi!
So I've finally got my Logitech Quickcam 4000 pro to stream video, but I
can't get any sound from the microphone. The USB sound is loaded as a
module (snd-usb-audio) at startup, and I think that's all I should need.
The usbaudio is registered by the kernel:

Jun 8 22:51:47 debian kernel: usbaudio: warning: found 1 of 0 logical

Jun 8 22:51:47 debian kernel: usbaudio: assuming the channel found is
the master channel (got a Philips camera?). Should be fine.
Jun 8 22:51:48 debian kernel: usbaudio: registered mixer 14,16
Basically I've tried "cat < /dev/dsp1 > /dev/dsp" and I can't hear
anything (my sound is working fine). I'm thinking that it's a silly
volume problem, except that I've tried adjusting the mic settings in
alsamixer to no avail. Should there be a usb mic setting in there?
Any help would be appreciated,
Thanks
