I am trying to get an audio output from a Mac Mini 4,1 (mid-2010) running Ubuntu server 22.04 with a minimal Gnome desktop environment. In particular I want to get sound over the HDMI output.
In the settings app I can select
- HDMI / DisplayPort3 - Built-in Audio
- Digital Output (S/PDIF) - Built-in Audio
- Speakers - Built-in Audio
but none work. I have checked that output levels are reasonable using alsamixer and that the speakers are not muted.
The output of sudo alsa-info --upload is here.
aplay --list-devices gives

Here are some general questions:
- Given that I started with an Ubuntu server installation and added a desktop environment afterwards, do I need to setup something manually to get audio running?
- Is any setup specific to the Mac Mini hardware required?
