Ok, so running mi piZero on piCorePlayer fixes the problem, but if I click on a Apple lossless file playing, it does display that it converts the song to FLAC with lower bitrate… So the same as the -e alac option on m2p…
Maybe piCorePlayer corrected the bug by forcing conversion to FLAC?
@rwanou: No, PiCorePlayer does not force conversion to FLAC. Have you installed the Squeezelite Extensions and the FFMpeg libraries on the Main Page of the PiCorePlayer web interface? I think, some of this is necessary to be able to play ALAC files.
If you have installed these things and it still converting them to FLAC, check your settings in Logitech Media Server (Settings –> Player –> Audio).
Glad it helped. There is an option for updating the „Squeezelite Extensions“ (playback of WAV/AIFF, FLAC, MP3, OGG and AAC) on the Main Page. But I think they are installed by default, so there’s no need to install them manually.
