1. Have you look up your HAT documentation and configure the necessary overlay file?
   
2. Under players page, if you see this "Uninstall Pulse" button in red, click on it.. Wait patiently for the operation to finish, and then refresh the page. If your HAT is configured properly the audio device should pop up in the list.

It seems that RPi5 has this problem with audio devices on newer builds (1.4.x), RPi4 doesn't have this problem but I'll try another build for RPi5. Actually, a wanted to try RPi5 because i didn't really had the time to play with it and I wanted to tryout mpd compiling speed against RPi4... It is quicker but unfortunately I have yet to setup nvme ssd, perhaps it will be significantly faster.
This is config.txt with little changes:

I don't know which overlay to put there because on 1.3.1 (RPi4) I've entered generic i2s RPi dac overlay and it could show this in audio devices no problem.
Also, both hdmi audio outputs are enumerated and accessible. Here, nothing...

I have connected Amanero USB and then it shows as audio device and I can save this config, myMPD can be started but it's not connected to MPD.

Reboot fixed this and now library is being scanned... I added only one NFS share from network but it's huge...
Now I need to fix i2s DAC connection...
