I have followed the instructions at to no avail and submitted a bug report. I've also tried running alsamixer and unmuting a few more things, but that didn't work. I've tried to upgrade alsa sound drivers by running: sudo add-apt-repository ppa:ubuntu-audio-dev/ppa sudo apt-get update sudo apt-get install linux-alsa-driver-modules-$(uname -r) however on the last command: $ sudo apt-get install linux-alsa-driver-modules-$(uname -r) Reading package lists.

Done E: Unable to locate package linux-alsa-driver-modules-3.2.0-24-generic-pae E: Couldn't find any package by regex 'linux-alsa-driver-modules-3.2.0-24-generic-pae' What should I do to try get sound functioning?

This is the output of my alsa-info: I've tried many other solutions as well but nothing seems to get alsamixer back, nevermind trying to get the audio to work again. When alsamixer was still working I did check the levels and it was not a case of the channels being muted. L4d2 Uncut Patch Multiplayer. Edit • /usr/bin is in $PATH.
