    audio capture in my gentoo linux does not work, audio playback works fine

    I tried arecord (directly go through alsa API) and skype (via pulseaudio), no sound is recorded what so ever

    I also tried to fiddle around in alsamixer capture device settings: I tried to use arecord with every mic in the alsamixer config dialog (I got four of them: Mic B, Mic C, Mic E and Mic F), none of which worked

    anyone successfully captured audio in linux (using any distribution)?
    (don't know whether this belongs in Lenovo/IBM or Linux forum)

    My bet it would belong in the Linux forums. You might get a better response on IRC as well. By the way, Gentoo huh? I once get sick of all the fiddling and compiling for little to no gain and switched to Arch recently :)

    I did use google talk on my W520, so it works. Though there still seems to be a timing problem, audio sometimes dies for a few minutes and then comes back spontaneously. Fedora 14, newest alsa release.

    for me, gentoo is all about the sense of control: you can explicitly decide what feature you want to compile in, and the ease of looking at any source code you installed

    thanks for the info guys, will give fedora a shot

    upgrading linux kernel from 2.6.37 to 2.6.38 fixes the problem
