GOOD news!! I found a workaround that could be useful for others with the same problem as well as for finding the cause/solution.
I noticed that I do get audio over hdmi when I close the laptop with the hdmi cable connected. It then goes to sleep. When I open it the audio over hdmi magically works!
Is there any details I can post for the ubuntu devs so they can find out what causes this bizarre issue?
