View Full Version : Onboard sound not working on laptop
Oct 31st 2007, 04:13 AM
I have a Toshiba laptop (model - Satellite A135-S4427) that the sound is not working on. When I mouse over the Mixer icon in the task panel it says (rhetorically) "Mixer cannot be found".
have any ideas?

Edit the /boot/grub/menu.lst file. Add acpi=off to the end of the first uncommented kernel line in /boot/grub/menu.lst file:
kernel /boot/vmlinuz-2.6.20-16-generic root=UUID=a2357a43-de81-4157-91ff-4fe745f01a79 ro splash acpi=off
Save and reboot. See if that makes a difference.

I just tried this on my desktop as I have the same error but it made no difference? Any advice?

Sounds like a similar problem I had with my Acer. Check what sound card you have:
lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
This is the output for mine. I had to download and compile the new alsa drivers directly from the alsa website. To make it easy I found a couple of scripts in the ubuntu forum that will do this for you:
Let us know if this works for you. Please remember that if you run the scripts you must use 'sudo'.

Thanks, will try that when I get home from work but from what I remember I have no sound cards listed when I do a hardware print, can't remember what print command exactly it was now...

That print command would be the lspci :)
