I added this to the "One Hundred Paper Cuts" project. We've been struggling with this bug for almost 4 years now! Even if it is an Alsa bug, there has to be some sort of fix that the Ubuntu guys could implement. Having to manually enter commands or run scripts every time you switch audio sources is not something a new user wants to do (especially if it's an IR controlled HTPC).
