Mac mini 4,1 (2010), Intel Core 2 Duo CPU P8800 @ 2.66GHz, 4GB RAM (2x2GB)
Running Ubuntu 22.04 LTS.
2 internal drives: 120GB SSD for the system and 500GB HDD for music.
N/A - no networking issues
Denon AVC-6700H via HDMI (also use other endpoints from Roon, these all work)
I am not able to get any audio out of my Mac Mini Core running Ubuntu 22.04 LTS. There are a number of audio devices showing up via ALSA, however the only one that actually works is CS4206 Analog (which is the internal speaker, mono, inside the Mac mini)
According to lspci I have the following sound card
00:08.0 Audio device: NVIDIA Corporation MCP89 High Definition Audio (rev a2)
Does anybody have any experience of this issue or know how to fix it? It is the last unresolved problem I have encountered, having switched from MacOS to Linux to enable upgrading my Core from Roon 1.8 to Roon 2.0.
