I'm actually trying to get a 5.1 setup working without passthrough, if I use mplayer with passthrough my receiver behaves just fine, but I am trying to send the 6 channels from the computer.
I was actually told that the current ALSA driver for radeon's hdmi does not support more than 2 channels, and that would explain why I'm getting this behavior. Is that true though?
Yes.
However, strangely your log output seems to show the intel's hdmi parser being used instead:
ALSA sound/pci/hda/patch_intelhdmi.c:842: hdmi_setup_stream: NID=0x2, stream=0x1, new-format=0x11
Were you just trying some patch at the time?
yes Wu gave me a patch to try against the kernel, I'm guessing this is the reason you see something unexpected.
Did 6 channels work with that patch? (possibly with a wrong channel order)
Also, could you provide the patch? (so that I won't ask you or anyone else to test unnecessary stuff :) )
I wasn't able to locate the original thread in archives.
Since I just moved to jack/rca cables I'm in no hurry anymore, but is there any reason why the driver cannot work with more than 2 channels?
I don't really know (it is simply not implemented).
Anything I could do to help with that?
Possibly. But see above, so that we won't try the same things you already tried :)
