AMP2 - No sound in Raspberry OS lite - Sound in Raspberry OS desktop

I have the strange behaviour that with a Raspberry OS desktop I do get sound from the AMP2. But with the same OS but the Lite version I cannot get any sound comming from the AMP2.

On the Raspberry OS desktop I left everything default and only set the dtoverlay=hifiberry-dacplus in the config.txt.
On the Rasberry OS lite I do have some other software installed and UART enabled in config.txt (has to do with a lit button I want to use). But this shouldn't be of any interference. And also set the dtoverlay to the same as the desktop OS in config.txt.

What am I missing? Checked alsamixer and digital volume was set at 100, decreased it to 25, so not to blow my speakers/ears.

aplay -l shows the Hifiberry as it should.

Anything missing from Raspberry OS lite that should be installed manually?
