View Full Version : [ubuntu] No sound through headphone Jack. Gateway T-1625, STAC9250

September 2nd, 2010, 03:24 AM
I am not getting any sound output from my headphone jack. I realize this has been a common problem for many people, but i have searched and searched forums and cannot find anything that works. The line "options snd-hda-intel model=eapd probe_mask=1 position_fix=1" added to the alsa_base.conf file seemed to solve the problem for people with Sigmatel Stac9250 soundcards. This did not work for me. I am a new ubuntu user running lucid lynx with the most current version of alsa (1.0.23).

Use the alsa-info-script to provide detailed information.
Run this command in a terminal:

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh
Enter your user password when prompted. Choose the upload option and provide a link for the output.

If you would please follow the alsa-upgrade link in my sig to get v. 1.0.23
Report your progress.

Followed all the steps from the link in your sig. Alsa is completely updated to 1.0.23. Still I get no sound. I've been working on this all night and it seems it probably has to do with setting the correct model and options for
options snd-hda-intel model = ??

Everyone with the Stac9205 codec seems to be getting their headphone jack to work by setting the model to "eapd", but this is not working for me.

Here is a copy of my Alsa_Base.conf file:

am I overlooking something?

Please remove that line from alsa-base.conf

options snd-hda-intel model=eapd probe_mask=1 position_fix=1
Replace with this:

options snd-hda-intel probe_mask=1
options snd-hda-intel enable=1 index=0 model=lenovo
Or this:

options snd-hda-intel enable_msi=0 model=eapd
