I really like to use my laptop (Aus 1215B) as my media centre and I like it running perfect. My problem is that the audio won't come out, it doesn't even show HDMI hardware on the Sounds preferences. When I was on 12.04 it used to play with no problem, I only had to switch, but now on 12.04.1 it doesn't.
I haven't installed proprietary drivers because they don't work, they fail most of the times (at least with me) and I didn't had to before updating my ubuntu.
I am almost sure that the update from 12.04 to 12.04.1 may have nothing to do with it, even because there were other updates that may have caused but I won't take notes. But I'd like to know if someone knows what happened and how do I solve it?
