[diwic] hdmi audio disabled in the radeon driver by default? investigate why?

[David Henningsson]

According to this blueprint [1], I'm supposed to figure out why hdmi 
audio was disabled in the Radeon driver.

This is more of a video driver issue; so I suggest you reassign it to a 
video driver person for more in-depth information. But in short, 
enabling hdmi audio broke video output somehow for some people. What I 
do not know is if this video breakage was actually a regression, showing 
up as a result of changes in the video driver, or if it was this way 
ever since HDMI audio was added to the driver.

Meta-bug is 864735. Dri-devel announcement here [2].
