Comment 18 for bug 33719

I trouble with a fresh Gutsy install on my Toshiba a200 (with intel's IHC8 family soundcard).

my speakers worked but my headphone jack wasn't being detected or showing up in the alsa mixer, nor was it working. Speakers didn't mute when I plugged my phones in.

But this fixes a lot of problems with these sound cards, because it ends up hooking you up with the latest alsa drivers, which i found hard to install elsewhere...
