No sound Ubuntu 10.10

Hi,

Please try the following procedure:

1. copy-paste the following command into the Terminal:

gksudo gedit /etc/modprobe.d/alsa-base.conf

2. and add these lines to the end of the /etc/modprobe.d/alsa-base.conf file:

# Keep snd-pcsp from being loaded as first soundcard
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=3stack-6ch-dig
options snd-hda-intel enable_msi=1

3. Then REBOOT and retest sound using both headphones and speakers

4. In the gnome-alsamixer application, make sure to unmute all channels and increase the volume on all channels

5. If the 3stack-6ch-dig alsa-base.conf option does not work, please try one of the following model options, reboot your pc and retest sound using both headphones and speakers. Only test 1 model option (for example: model=m51va) at a time between reboots!
