I've got Dell Vostro 3360 laptop, and internal mic doesn't work. I use 3.8 series kernel.

When I try to record sound from mic I get only weird noise. All sliders in alsamixer are 100% and capture is ON.

alsa-info.sh script output could be found here.

I guess it could be fixed by specifying model for snd-hda-intel module but I've got no idea what model I should specify.

Any idea?

  • Are you sure it isn't a hardware problem? – peterph Apr 8 '13 at 12:33
  • @peterph any idea how to check that? – post-factum Apr 8 '13 at 13:49
  • Try with external mic. Alternatively try another installation (different distro or windows if that is an option). – peterph Apr 8 '13 at 15:51
  • It works indeed. I've compiler 3.9-rc6, and my mic works OK now. I think it happened due to large HDA sound rework in 3.9. Fortunately, I can use -rc kernels :). – post-factum Apr 8 '13 at 20:18

3.9-rc6 kernel fixes this issue.
