This has never worked. The HW works fine with older kernels and proprietary drivers. Tried with VGA connector, and with with the radeon.audio=0 without change in the behavior.
Which older kernels worked? Can you bisect?
3.10.20, but like said it's with proprietary drivers. OpenELEC "distro" to be exact.
