Bug Description
After the 12.04 Update my HDMI audio stops working anytime I turn off or on, my 2nd monitor(plasma TV)
System Settings>Sound - Output
HDMI audio disappears from the list when monitor is turned off or on and does not reappear.

I'm guessing it has something to do with sink detection and ATI video
The only info I've found is after running pactl list

I checked before and after. The only difference is
hdmi-output-0: HDMI / DisplayPort (priority: 5900, not available)
Where "not available" is the only change I found.
Removing cable from HDMI socket and plugging in again, restores audio.
Logging in and out again restores audio.
