I've been trying amd-staging on and off for a while in the hope of getting
HDMI/DP surround sound working. There seems to be very few people trying
amd-staging and even fewer trying surround sound as I haven't seen a single
mention of it anywhere. Is it even supposed to work yet?

Stereo output is working but multi-channel LPCM only appears on my receiver=
 as
stereo and AC3 pass-through doesn't work at all. I had all this working on =
the
same system with my old HD 4670 and I've made do with S/PDIF from my on-boa=
rd
sound in the meantime. I've tried directly with ALSA and via PulseAudio.

The latest kernel I've tried is 4.11 with
b382281b45ec359deeeeef715b182322f4fa9566. I've found alsa-lib and friends c=
an
make a difference in the past so I just tried 1.1.4.

I'll attach some details. Note that I have a stereo monitor plugged into the
HDMI port and my receiver in the first DisplayPort. I obviously select the
right output when testing!
