I have a Philips USB webcam with microphone. When I plug it into my computer it is recognised. Video is registered as /dev/video0. It also says "registered new driver usb-snd-audio". But where does the audio go? There is no mention of an associated device. I can see the microphone in KMIX, but only as an input! There is no output associated with the mic. If I do "cat /dev/dsp > test", the file stays empty.

How can I get sound from my mic?
