I’m trying to use a Zotac CI331 as Roon Bridge endpoint. When using Windows 10/11 this works without any problem, but I don’t like the big footprint of Windows for a mini PC with one specific task: Roon Bridge. However, when I try to use Linux the HDMI Audio output is not available, the one output that I need for multichannel audio support. The Zotac CI331 uses the Intel High Definition Audio specification (Digital 8 Channel Audio Lossless Bitstream via HDMI), so I assume Linux should be able to use the HDMI Audio output. So far I tried ROCK, Ubuntu and DietPi. All fail to support HDMI Audio.
Is there someone here who can point me in the right direction? Thanks!

I think you nailed it. The “core” audio, analog only, is available. I was looking for a cheap Roon bridge with hdmi/multichannel support. This is possible with Windows 10/Windows 11. I hoped for ROCK. But as long there’s no Linux support for the converter chip all I can do is hope, I’m afraid.
It looks like that the previous CI331 model, without the new BIOS with UEFI and hdmi 2.0 support, did all I wanted.
