Argh, after upgrading kernel to version 2.6.32-24 sound stopped working. I ran Alsa upgrade script 1.0.23-2 with -r option and rebooted, and then tried to run the update again. Now I have run the script numerous times, tried snapshot and everything but it just doesn't upgrade alsa anymore. I'm stuck with version 126.96.36.199 and aplay -l doesn't even show my Intel HDA Audio that I use for HDMI
Edit: Yay got it upgraded! Didn't realize I have to remove some of the Alsa packages manually first.
