(It's a Sony Vaio.)

Recording (more correct: capturing) of sound doesn't work (I have tried all combinations of the input (capture) controls in the mixer). It's quite surprising, because if I turn on the _output_ control for the microphone, the sound is indeed echoed to the output.

Tested with a plugged-in microphone with:
arecord from aplay-1.0.21-alt1, audacity-1.3.7-alt1, skype-2.1.0.81-alt1.

Recording under 2.6.30-std-def-alt15 works. (So, this is a workaround for the 5.1 branch. But that kernel, as respects sound, has the problem https://bugzilla.altlinux.org/show_bug.cgi?id=23705 .)
