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.

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