Created attachment 107088 [details] dmesg log for drm and radeon lines On kernel 3.9 using radeon.audio=1 can produce display and audio on HDMI output. Using 3.10 and 3.11-rc3 with this parameter breaks HDMI output (no screen). Without this parameter HDMI display works fine, but no audio.

Can you bisect?

Do you have some second monitor or other machine to ssh the first one? I'd like to see output of command avivotool regs hdmi when using 3.9 with audio=1 and then using 3.10/3.11 with audio=1.

Created attachment 107104 [details] avivotool regs hdmi output on kernel 3.9 This is with radeon.audio=1 kernel parameter with kernel 3.9.9
Created attachment 107105 [details] avivotool regs hdmi output on kernel 3.10 This is with radeon.audio=1 kernel parameter with kernel 3.10.3
@Gabor: can you boot 3.10.3 and call: avivotool regset 0x12c44 0x00000033
(Please make it *after* connecting HDMI display, after it breaks)
@Rafał: It's working. After switching to mirroring, or to HDMI only, and entering this command, the display starts working with sound.
