Help needed on debugging

After quite some usage, I now want to dive into the tech reason behind an issue on my end.
Some songs in my LMS server(s) multiple, do not play on all squeezelight players ( multiple versions in picoreplayer ).
I have started to debug and found a logifile entry:
[16:19:20.346360] output_thread:664 open output device: hw:CARD=sndrpihifiberry

Can someone tell me if the squeezelight ( both Ralphy's versions ) is incapable to play this m4a file ( made by foobar200 ) ?
And why squeeze player on my android does play this file without problems ?
The error seems to be absent in HD flac files , 44.1*16*2 flac and mp3 but is in all m4a ans some ogg files.
If there is a good piece if info to read for me as education, please send me the link, in stead of spelling out what is already there.
