I made it to the second part of step one in the Sound Troubleshooting Procedure: "If you upgraded ALSA using the command above...." and after rebooting, I found that I can no longer access alsamixer, whether from the command line or gnome mixer, and the sound still doesn't work. ALSA is installed and updated to the latest version.
Here's what I got after executing
Code:
wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh; chmod +x ./alsa-info.sh; ./alsa-info.sh
It looks like some drivers or something are missing here, but I don't know what to download to get them:
