ALC889 analog sound codec not working on Acer Aspire 6935g in Ubuntu 9.04

Asked by Elia Daniele

Hello everyone!
I can't hear any kind of sound on my ACER6935G notebook.
I've a dual boot with ubuntu 9.04 and Vista home premium, but under ubuntu the sound doesn't come out!
The sound card detected is an Intel HDA ALC889 Analog:

elia@elia-laptop:~$ aplay -l
**** Lista di PLAYBACK dispositivi hardware ****
scheda 0: Intel [HDA Intel], dispositivo 0: ALC889 Analog [ALC889 Analog]
  Sottoperiferiche: 1/1
  Sottoperiferica #0: subdevice #0

Please, is there anybody that could help me?!?

Hi,

Please try this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (copy/paste each command into the Terminal and then hit <enter>)

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

Add these 2 lines to the end of the alsa-base.conf file:

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=auto

If those alsa-base.conf options don't work, please try these 2 lines instead:

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=acer-aspire

If it still does not work, you can try upgrading alsa to v1.0.19 using this link:

Don't forget to reboot your pc after every change you make on the /etc/modprobe.d/alsa-base.conf file.

Regards,

Mark
