Speaker/Headphone Port Issue

**colin.bellinger** · August 26th, 2008

Hi, I have a sz640 running Ubuntu 8.04. The cat /proc/asound/card0/codec#* | grep Codec output is:

Codec: SigmaTel STAC9872AK
Codec: Conexant ID 2c06

Initially I had sound, but not through the headphones. After adding

options snd-hda-intel model=vaio

I have no sound.

Is this thread still active?

I hope this thread is still active! I've tried the steps mentioned above on my toshiba satellite laptop, but still no sound out of the headphones. Perhaps I'm not adding the the right model after: options snd-hda-intel model=MODEL

I've tried Satellite, satellite, and toshiba. No luck so far.

When I try to find out what sound card I have this is what I get:

cat /proc/asound/card0/codec#* | grep Codec
Codec: Conexant CX20551 (Waikiki)

Anyway, I'm a noob to most of this, so if someone could point out what I'm doing wrong I'd appreciate it!

Thanks

1. Let's find out which model of sound card you use:

Code:

cat /proc/asound/card0/codec#* | grep Codec

The output on my sony vaio sz6 looks like:

Code:

SigmaTel STAC9872AK

Of course yours might look differen.

2. Search for your model on this site: http://www.mjmwired.net/kernel/Docum...figuration.txt

3. Take a look at the model type options and take the one that fits best to your laptop, for example 'sony' or 'vaio' or the like.

4. Open up /etc/modprobe.d/alsa-base:

Code:

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

and add

Code:

options snd-hda-intel model=MODEL

to the end of the file, assuming it is an intel hda sound card which is most likely the case with your sony laptop. Restart your laptop and let's pray it has fixed your problem.

Great tutorial Nepherte. Thanks a lot for your instrucions. They worked like a charm with my brother's laptop. It is a sony VGN-NR310FH and i'm using Intrepid Ibex.
