Tant per a Ubuntu com per a Linux Mint ... i LliureX serveix la "xulla":

After having some trouble finding the HDD which I wanted to replace by an OCZ Vertex 2 I also had difficulty getting my speakers to work. The headphones worked fine but no sound from the speakers. After searching for quite some time I finally found the solution:

Obrir una consola o terminal i escriure:

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

Desprès escriure:

options snd-hda-intel model=auto


I also added the ubuntu-audio-dev repository but I’m quite sure this is not what fixed my problem…

The Ubuntu Kernel Team produces what they call "Crack of the Day" builds of alsa-driver code. This is the latest development code that is being worked on "upstream" and has all the most recent fixes to hardware issues. We ask users having audio problems to install these builds in order to help us identify whether the issue has already been fixed or if it's also an issue upstream.

Installing

Install with Command Line

Adding the ppa

Obrir una consola o terminal i escriure:

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa

Desprès:

sudo apt-get update

Install the linux-alsa-driver-modules package

Obrir una consola o terminal i escriure:

sudo apt-get install linux-alsa-driver-modules-$(uname -r)

Note: After installing the linux-alsa-driver-modules package, your system needs to be rebooted.
