I enabled audio component logging and that produced this file: http://ix.io/3Fgk

I have a 4k HDR TV with ARC but not eARC, a Pioneer SC-1224 AVR capable of 4k60p but not HDR and 7.2 multichannel audio and 2 Rock64's.
One Rock64 (hostname: soundserver; IP address: 192.168.2.34) is running Debian Bookworm with kernel 5.15 (from experimental) and PulseAudio in system mode. I've downgraded PA from 15.0 to 14.2 to match what's running on LE. It has 2 sound cards, HDMI and SPDIF although I've never gotten the latter to output any sound. I'm using the simple-card alsa card definition from LibreELEC.The other Rock64 (hostname: kodi-rock64; IP address: 192.168.2.32) is running "LibreELEC (community): nightly-20211111-b431638 (RK3328.arm)", but I've also tried it with LE 10.0.1.
What I've used so far is that both are connected via a HDMI cable to the AVR and the AVR is connected via HDMI cable to my TV.
That works really well, except I can't properly view HDR content. If I connect kodi-rock64 directly to my TV, I do have (4k x265) HDR, but then I won't have multichannel audio.To get both HDR and multichannel audio, I want to connect kodi-rock64 directly to my TV, but send the audio over the network to soundserver which then sends it to my AVR.
I tried following the instructions from https://wiki.libreelec.tv/configuration/…network-sending but I never got the tunnel-sink, only the null-sink.
My PC can connect and use PA on soundserver to play sound, so I'm quite sure I've set it up correctly. I have now set "default-server = tcp:192.168.2.34:4713" in "~/.config/pulse/client.conf", and now I do see both the HDMI and SPDIF sinks
But in Settings/System/Audio, Audio output device I only see the SPDIF card, which doesn't work [for me|afaik]. If I blacklist "snd_soc_rockchip_spdif", then the SPDIF card is gone, but that still doesn't get me the HDMI sink to select in Settings/System/Audio.
What do I need to do to get the HDMI soundcard to appear in System Settings, which then (hopefully) allows me to watch 4k HDR content with multichannel audio?
