About HDMI audio: does it work on radeonsi as well? Because even if I boot with radeon.audio=1 I get no sound, the device doesn't even appear in pulseaudio...
I've zero issues too with both DPM and HDMI Audio with my Sapphire 7850. Works for me with Kernel 3.12rc7. Kernel parameter: "radeon.dpm=1 radeon.audio=1"
I'm using pavucontrol (PulseAudioVolumeControl) to easily swith my playback streams between my different output systems. Maybe it helps you.
