Sorry, this is an extraordinarily boring post for everyone but a nice reference for me and it might help someone in the same situation as me.
I recently upgraded to Ubuntu 7.10 on my Toshiba Tecra A8 and found that sound from my speakers weren’t working (although the headphones were). I had a bit of a look around and had to cross reference a few bits on information I’d found in order to get it to work.
But to cut to the chase, I opened gedit as root by typing the following in the terminal window:
sudo gedit
the opened the file
/etc/modprobe.d/asla-base
and added the following line to the bottom
options snd-hda-intel enable=1 index=0 model=basic
I then ran
update-modules
Although I’m not 100% that did anything. And then I rebooted and it worked.
Hope that’s helpful to someone.

Great instruction.
I simply typed in on my Ubuntu 6.10 (Tecra A8) and after reboot the sound works.
Thanks

Does the jack sense work with that option? The jack sense didn’t work with the basic model when I was troubleshooting this issue (although I didn’t add the other parameters). Instead, I used this line:
options snd-hda-intel model=hippo
The jack sense works properly so the speakers are muted when I plug in my headphones. Also, I can choose to unmute the speakers even with the headphones if I want to.

Hi Akira, are you talking about the headphone jack?
My headphone jack always worked, it was just the speakers that didn’t. However the speakers would not mute when I plugged the headphones in - you have to do that manually so perhaps your solution is better than mine.
Thanks for the info though.

Nan, I actually just tried this again with Akira’s suggestion (after upgrading to 8.04) and yes, it work perfectly.
