I installed Ubuntu 10.04 on my Toshiba laptop. Love it!

Video, wi-fi and everything else seems to be working fine. My one problem is no sound. I've spent a couple of days trying various fixes, updates, etc. and nothing has fixed the problem. I have the files for alsamixer (found files in my home folder) but it won't launch.

aplay -l
aplay: device_list:223: no soundcards found...

lspci

00:14.2 Audio device: ATI Technologies Inc IXP SB4x0 High Definition Audio Controller (rev 01)

alsamixer
cannot open mixer: No such file or directory

Any help would be appreciated.

I added the line

options snd-hda-intel model=3stack

to the file

/etc/modprobe.d/alsa-base

The file now contains two lines

options snd-hda-intel model=Toshiba S06
options snd-hda-intel model=3stack

I rebooted but still no sound.

You need admin privileges to edit that file. Try:

$ sudo gedit /etc/modprobe.d/alsa-base

I was able to edit the file but still no sound.

As mentioned the file has two lines...

options snd-hda-intel model=Toshiba S06
options snd-hda-intel model=3stack

I rebooted but no joy.

I have two sets of alsa files, one set in the Home folder and one set in the File Systems folder. Should I delete the set of files in the Home folder? Could this have anything to do with the sound problems?
