I am running Archlinux (kernel 3.10.3) with ati driver 1:7.1, on an ASRock E350M1 Mini ITX board that has a Radeon HD 6310 on-board. (From the evergreen family, feature matrix shows "DONE" at HDMI audio). Further specs: processor: AMD Fusion E-350 chipset: AMD A50M (Hudson-M1) Attached to the board is my TV set, via HDMI. Vanilla install works fine, except: no audio via HDMI. The standard alsa device is configured as card 0, device 0. But poking around (aplay -l, cat /proc/asound/cards) shows me this should be card 0, device 3. That's something that needs fixing. But mplayer -ao alsa:device=hw=0.3 <some file> returns no errors but I hear no sound... Reading the (excellent) arch wiki (https://wiki.archlinux.org/index.php/Radeon#HDMI_audio) I was recommended to add radeon.audio=1 to my kernel parameters. Without it, I see that I /sys/.../parameters/audio = 0. Setting the kernel parameter does flip this parameter into 1... But: as soon as the kernel loads with this parameter set, the screen goes blank with no signal detected by my TV. The system continues booting as per normal. Logging in through ssh and trying to play the same audio file: still no sound from my TV set. Switching the TV off and back on or unplugging and plugging back in (all this while mplayer runs), still no sound. Just for fun: also setting radeon.tv=0 as kernel parameter does not help. Same thing... When I run mplayer, nothing awkward shows up in journalctl -f Any clue as to what to try next?
Is this a regression from 3.9 maybe? We have some similar report: https://bugzilla.kernel.org/show_bug.cgi?id=60687 Could you try using audio=1, wait for blank screen and execute: avivotools regs hdmi ? I hope Arch provides that tool, in case it doesn't, there is URL: http://cgit.freedesktop.org/~airlied/radeontool
Yes, archlinux has radeontool in it's repository ;-) The result is attached.
Created attachment 83643 [details] avivotool regs hdmi output when failure happens
@Willem: after connecting your HDMI display (and experiencing failure) please call: avivotool regset 0x7044 0x00000033 I'm 99% sure it'll solve your problem, so you can use it as a temporary workaround. I'll work on the real fix.

This is still a problem on my Turks (6670) card, running kernel 3.11.1 (fedora version)
