Comment 17 for bug 315971

I'm also affected by this issue, also in Jaunty (x64). Once I'd unmuted the sound controls using gnome-volume-properties, 'sudo alsactl store' didn't work for me; I had to change the permissions on '/var/lib/alsa/asound.state' first (to 0777) before running the 'alsactl store' command as myself, then change the perms back to 0744 when done.
