Hi, for my webcam (Nam Tai E&E Products Ltd. or OmniVision Technologies, Inc. Sony Playstation Eye) I am using guvcview 1.4.5. The Webcam is attached via usb to my PC.
Since the webcams audio device was not listed in the according drop
down menu of guvcview I browsed through the kernel (2.6.39 vanilla)
config and found, that I forgot to include the usb-audio module.
After recompiling and rebooting, guvcview now lists the webcams audio
device (but still no sound).
Unfortunately it kills any sound when using mplayer, which says:

When using vlc to watch tv (dvbt) the sound is interrupted
(stuutering) and/or heavily distorted (sound reminds me on sandpaper
with glas instead of the sand...;)
Before including usb-audio everything (with exception of the missing
audio device of my cam...) was working fine.
I think I will get lost without any help of the external world... ;)
Attached this email you will find my compressed kernel config.
Thank you very much in advance for any help!
