Toshiba A100-147: intel-hda trouble

Asked by Ben Page

Hello, can somebody help me? I am totally new to linux and i can't get my sound working properly on my Toshiba Equium A100-147.

When i first installed Ubuntu the sound worked, only it was really quiet. Now I followed the instructions at https://help.ubuntu.com/community/SoundTroubleshooting and my sound is no longer working at all. It looks as if my sound card is no longer being recognised by the machine.

Every time i try to use modprobe i get the following errors.

Can you help please?

Ben :
Could you run the following command and post the output please ?
grep Codec /proc/asound/card0/codec#*

You should get something like this :
$ grep Codec /proc/asound/card0/codec#*
/proc/asound/card0/codec#0:Codec: Realtek ALC268
/proc/asound/card0/codec#1:Codec: Generic 11c1 Si3054

Hi Jeff, I ran the command and below is the output.

$ grep Codec /proc/asound/card0/codec#*
/proc/asound/card0/codec#0:Codec: Realtek ALC861
/proc/asound/card0/codec#1:Codec: Generic 11c1 Si3054

Unrelated: The sound on my machine started working again, just very low like before it stopped completely.

Hi Ben,

Thanks for the information.

The problem is following : You tried to recompile alsa modules yourself and something goes wrong.
Now alsa is broken :-(

The easiest way to fix alsa is to reinstall Ubuntu. But may be it's not possible...
You could avoid a reinstallation, but you have to tell me precisely what are the instructions you followed at https://help.ubuntu.com/community/SoundTroubleshooting and so what you have done.

Once alsa "works" again (that is to say no more errors when modprobing the module), you just have to enter the following commands in a terminal:
sudo apt-get install linux-backports-modules-generic
sudo gedit /etc/modprobe.d/alsa-base
Then replace the following line :
options snd-hda-intel
by this one:
options snd-hda-intel model=3stack
Reboot and test if sound works.

Basically, it will install alsa 1.0.15rc3 and modify a parameter of the hda intel driver.

Your problem has already been reported in bug #138322 :
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/138322

By the way, I am Fred, not Jeff ;-)

Oops, :o
sorry Fred.

I can't really remember which instructions at https://help.ubuntu.com/community/SoundTroubleshooting that I followed, so it will probably be easier to re-install Ubuntu. I'll do it in a week or so when I get time, and then if the commands work for me I will mark this question solved.

By the looks of the bug report what you have told me to do should work, thanks for you help, now I can enjoy my music again.
