no 5.1 sound over hdmi (only PCM 2.0 send to receiver)

Hi,

i just realized that my 5.1 setup (which worked before) stopped sending PCM 5.1 oder hdmi to my receiver.

The Receiver says that it only get's PCM 2.0 from the hdmi signal.

Testing with gnome audio settings i can even see the audio level indicator move when i test anything else than left or right.

Speaker-test -c6 also just plays at left and right.

I sanity tested with windows to see if my receiver is the problem, but it seems to work flawlessly there.

The threads that i did find reporting a similar problem either didn't fix my problem, or did not get any solution.

Tried switching from pulse to pipewire (using pipewire right now) that also doesnt solve the problem. I'm a litle bit clueless right now.

Here some informations:

sudo fuser -v /dev/snd/*

                     BEN.        PID ZUGR.  BEFEHL
/dev/snd/controlC0:  username     F.... pipewire

since i switched to pipewire in the hope that would solve my problem, there is no pacmd anymore.. so no list-sinks etc. for now.
