No sound output picroft

Hallo!
I have installed picroft on a raspberry pi 4 and get no sound from 3,5 jack.
If I use pi OS instead, everything is ok!
I have read posts about this problem here on the forum and elsewhere , but I cannot get it to work.
Could someone please explain what I need to do?
I am familiar with terminal commands, but still consider me a novis.
Any Ideas?
