I didn’t file it as a Manjaro bug since I’ve seen it across the board of distros and kernels (4.11 was initial support I believe for the ALC1220) not sure exactly where on the stack the bug is to report to
try bypassing playback in Pulseaudio by playing audio direct to ALSA hardware
speaker-test command if can’t do it with an audio player)
no luck it wouldn’t work either, though I am not experienced with that tool

If you plug something into the rear line-out, it’s correctly recognised as plugged in there, but the actual audio seems to get routed to headphones. I use pavucontrol to switch output to headphones as a workaround.
It’s properly recognizing the port being plugged and I can select between front or rear for output and input. This did have me do some more thorough hardware testing with interesting results.
Rear speaker out (line out) won’t work at at all on linux (with any device)
Front panel out works fine (with both 2.1 speakers and headphones)
Rear mic in works fine
Front mic in works fine
Don’t have the setup to test the rear 5.1 or 7.1 ports
USB audio works
HDMI audio works
DP audio works
So for whatever reason the rear line out is just borked on the linux driver or audio stack?
I haven’t yet tested if disconnecting the front audio connector fixes the issue (Front panel connector is from a Lian Li 011-Dynamic) but since input works on both and it sees the ports I don’t think that’s going to be the solution.
