I want to use my RPi2 as 5.1 output device on my AV receiver and want to be able to send audio from my Arch Linux computer running PulseAudio in 5.1 to the surround system. The 5.1 output on the RPi seems to be unfinished but with LibreELEC’s applied patches I get full surround sound playing videos with the UI, nice! Now, I want to leverage this hardware support (had no luck with Xubuntu and none with Raspbian) to use the PulseAudio networking feature, good documented in the LibreELEC wiki.
But here comes the problem: "pactl list short sinks" lists only this:
0 auto_null module-null-sink.c s16le 2ch 44100Hz RUNNING
And guess what, it’s really a null device, I checked. So, any way to get the 5.1 output established to PulseAudio? Thank you!
