Update: I noticed I was using the desktop kernel this time, and reinstalled the default kernel. The audio now works fine (once this patch is installed). Works every time. This rings a bell, like I've had to do this to a system in the past. I don't really understand what desktop vs default kernel would have an effect on the drivers - from what I can read there doesn't seem to be anything in there.
