I already found the problem.
The sampling & bit setting in MPD was 192000:24:2.
Changing to 44100:16:2 and I have sound with MPD.
I don’t know what my setting before was – though I know I had to change this 4y ago to have sound without glitches.
Would you rather recommend 48000:16:2 or 44100:24:2?
Shairport was not working yet.
There I had to change the output from default to sysdefault and after a daemon restart airplay is working ok again.
Probably some settings got lost after power cut.
Any way to back up my configs and restore in the case of doubt?
