Hi all,

I don't find anything with google ...

LFS, ALSA-1.0.4, VIA82c686. I want to use a microphone for sound

In alsamixer, there is a mic channel. I use it for capture. It is not
muted, it is selected for input, and it has 100%.

Same in KMix.

Now i start audacity-1.2.3. I speak into the mic, and i can't see any

What i found is that the output of arecord -l might give useful

[root at ns1 /]# arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: rev21 [VIA 82C686A/B rev21], device 0: VIA 82C686A/B rev21 [VIA 82C686A/B rev21]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

Is any further information necessary, or is my fault already obvious
for the guru? ;-)
