(I don't know the details of this bug, but am just responding to comment #11) @Michel: Fixing regressions without introducing other regressions is a prerequisite for being sure of forward progress. Else it's possible we are going in circles. The policy on the linux kernel is: no regressions. So, we revert even fixes if they cause _new_ regressions.
Not being able to see your screen(s) seems like a bigger issue than having to set an option to enable audio. Although, audio support itself regressed working video for the bad cases originally, so audio support was a regression as well for some people.
