I am not sure if I did it right but now I don't even get hdmi sound
working anymore.
It is not listed in aplay-l, and dmesg gives me this:
[drm:radeon_dvi_detect] *ERROR* HDMI Type A-1: probed a monitor but
no|invalid EDID
I've attached the patch I used, since I could not used the previous
one I had to hack it, maybe I broke something?
(I have not set channels to 8 yet, just changed the parser)
Thanks,
John
