Quick test yesterday evening, I thought I could test display port, I got my DP to HDMI cable and plugged it into the AVR (Denon 4700H) and lo and behold, no more audio dropouts within 15 minutes!? I'll test more this evening and report back! The motherboard is Asus N100I-D-D4 and I'm on 12.0.1, use passthrough and 23,976.
Intel Alder Lake 2160p @ 23.976 Hz passthrough HD Audio dropouts (i7-1270p/N100)

It seems that they can't reproduce the issue:

@chewitt We tried reproducing this in our lab with ADLP->TV setup but we are not seeing the issue. Were you able to reproduce this issue without the AVR setup?

Just to follow up on cheeez findings. The new Libreelec 12.0.1 release included an important kernel patch discussed here:
No HBR Audio with LSPCON - Trying to collect information - General Support - LibreELEC Forum
It fixes HBR audio streams for Paradetech and Synapitcs LSPCons (DP to HDMI convereter chips). It also seems to cause PCM >2 channels to no longer be bit perfect. It changes the output timings. Other might find 12.0.1 with a converter behaves differently/better.
