http://askubuntu.com – I just upgreaded from 3.2.0-30-generic to kernel 3.2.0-31-generic, I noticed that the sound is not working with the 3.2.0-31-generic, but its working fine for 3.2.0-30-generic and bellow. here's my alsa-base.conf autoloader aliases install sound-slot-0 /sbin/modprobe snd-card-0 install sound-slot-1 /sbin/modprobe snd-card-1 install sound-slot-2 /sbin/modprobe snd-card-2 install sound-slot-3 /sbin/modprobe snd-card-3 install sound-slot-4 /sbin/modprobe snd-card-4 install sound-slot-5 /sbin/modprobe snd-card-5 install sound-slot-6 /sbin/modprobe snd-card-6 install sound-slot-7 /s (HowTos)
