Attached patch fixes multi-channel HDMI audio on my RX 460.
I was about to shower you with praise but sadly that patch made no difference here. :(
Maybe there is something else broken with DisplayPort audio?
Yes! I switched the outputs around (one was just using an adapter) and now it works! I really should have tried that sooner. This arrangement is fine for me as the monitor is just stereo anyway.
LPCM works and so does ALSA pass-through but PulseAudio is refusing to do pass-through for some reason. I've had it working in the past but I can live with that for now.
