Hi, |
2 |
|
3 |
for my webcam (Nam Tai E&E Products Ltd. or OmniVision Technologies, Inc. Sony Playstation Eye) |
4 |
I am using guvcview 1.4.5. The Webcam is attached via usb to my PC. |
5 |
|
6 |
Since the webcams audio device was not listed in the according drop |
7 |
down menu of guvcview I browsed through the kernel (2.6.39 vanilla) |
8 |
config and found, that I forgot to include the usb-audio module. |
9 |
|
10 |
After recompiling and rebooting, guvcview now lists the webcams audio |
11 |
device (but still no sound). |
12 |
|
13 |
Unfortunately it kills any sound when using mplayer, which says: |

When using vlc to watch tv (dvbt) the sound is interrupted |
46 |
(stuutering) and/or heavily distorted (sound reminds me on sandpaper |
47 |
with glas instead of the sand...;) |
48 |
|
49 |
Before including usb-audio everything (with exception of the missing |
50 |
audio device of my cam...) was working fine. |
51 |
|
52 |
I think I will get lost without any help of the external world... ;) |

Attached this email you will find my compressed kernel config. |
