No audio on Ubuntu 9.10

Any ideas as to why I can't seem to get any audio from my Ubuntu? I have a Dell Studio XPS 1645 and a fresh, hardly modified installation of Ubuntu.

 

Do you hear the startup Ubuntu jungle sound? What happens when you try to play audio?

 

I can't find any thread or anything that has the correct option line, so you'll have to figure it out yourself.

First run:

Code:

aplay -l | grep -i alc

It will return something like this:

Code:

card 0: Intel [HDA Intel], device 0: ALC663 Analog [ALC663 Analog]
card 0: Intel [HDA Intel], device 1: ALC663 Digital [ALC663 Digital]

Then take that number, 664 in my case, and find it in this list:
http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt

Then find an option that says Dell, or a generic one, and try it by editing /etc/modprobe.d/alsa-base.conf:

Code:

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

Put a new line at the bottom of the file:

Code:

options snd-hda-intel model=dell-whatever

Save the file, and leave the window open because the first option you try may not work. Open a terminal and run:

Code:

sudo alsa force-reload

This will reload ALSA with your model option that you just edited into alsa-base.conf. Try opening your sound preferences or mixer and see if all the levels are up and the speaker is not muted, and try playing sound.

Go back to the list of models and try a new one, replace model=dell-whatever with the new model to try. Then reload alsa again. Eventually it should work.

 

Hope This helps haven't tested it but i found it online a couple weeks ago:

Installing Ubuntu 9.10 Karmic Koala on the Dell XPS 16 i7 laptop is pretty straight forward. Everything pretty much worked out of the box. The only thing that needed to be modified to work was the sound drivers.
Sound:
To get the sound to work add the following to /etc/modprobe.d/alsa-base.conf:

Configure the sound card
Codec: IDT 92HD73C1X5
options snd-hda-intel model=dell-m6
options snd-hda-intel enable_msi=1

 

Hey !
Thanks a lot : those 2 lines did the trick for me on an XPS 1645 very similar to the one you should be receiving soon per your signature.

Tnx again & merry xmas to u all
