However these have barely been testing so should only be used if absolutely necessary.
This document describes installing ALSA from source code.
Any other kernel options regarding sound can be switched OFF.
Of course, you need a sound card that is supported by ALSA. You can download the sources from the front page of the ALSA home page: To make module loading permanent, you have to add these lines to /etc/(for Debian users, this means you have to create a file with these lines in /etc/modutils and the do update-modules).
I ended up downloading one from here but after a reboot, my sound icon was gone from the toolbar and no sound can be heard.
Before installing the ALSA modules, you will need to decide whether to install the latest stable or development drivers. In this guide we are going to use alsa-driver-1.0.25 as at the time of writing these are the current stable drivers.
Maybe updating ALSA or using another module will fix the problem.
If nothing works, you can define a new virtual pcm device in the .asoundrc file, which controls the volume on the software side.
Jump to: navigation, search This howto describes a workaround if your master volume doesn't work.
This happens if your sound card can't control the volume on the hardware side or the driver doesn't support this feature of your sound card.
