fc6 intel 82801g sound card problems


Hi there.

I'm running fc6 on a gateway M420 laptop. my kernel is 2.6.19-1.2895.fc6, recently updated. that may be the source of my problem, but I'm not sure what to do if it is.

I recently installed fc6, and everything was working fine, except my sound card. I could play sound fine, but as far as fedora was concerned, my sound card didn't have an audio in port. I thought I should do something about that, but I never got around to it. Recently, I updated my computer using yumex, and now my sound card won't work at all.

When I run system-config-soundcard, the sound card is detected, and described like this:
Quote:
Intel Corporation
82801G (ICH7 Family) high definition audio controller
module snd-hda-intel
If I play a test sound, I hear nothing. I am then asked if I heard the sound, and when I click no, I am told that automatic detection of the sound card did not work.

Any help would be greatly appreciated.

Whenever I read other peoples posts about nonfunctional soundcards, these things are usually asked for, so here they are, just in case it helps:

problem solved... somehow

good news!

after 2 days of the problem, no new system updates, and multiple reboots, I heard a chime come from my laptop. I still have no idea what the problem was, or how it got fixed.

upon further examination, my microphone line in now works too. how mysteriously wonderful!

UPDATE: scratch that, the microphone stopped working again. still no idea why...
