hdmi multi channel audio is supported for AMD gpus since kernel 3.13 ... provide the relevant debuglogs.

Optical can only du 2 channel pcm wise. AC3 and DTS are encoded surround signals that only need 2 pcm channels to send to the AVR which does the decoding.

Are my previous debug logs not the correct ones?

All channels are there. I see no AMD card in there.

Careful, SinCityHarley has nvidia, it was another poster (Tierry) with the AMD gear.

I hate those cross posters ... that scream "me too".
