Hello.
I have the same issue. Volumio does not find all my music in the /data/INTERNAL folder. I have no *m4a files… only FLAC and mp3.
I have consulted the logs, but there are no clues as to might be going wrong.
I have assigned ownership of all the folders and files within INTERNAL to mdp:audio. Folders have 775 permissions, and files have 644 at least.
Everything should be readable by mdp and the “audio group”, and folders are writable by the “audio group” (which includes users volumio and mpd).
Still, when I press “rescan” or “update” in “mymusic” under “settings”, music is not found.
What exactly happens when those buttons are pressed? What is the linux process (or volumio process) that is launched to perform the rescan of music? If I could launch the same process on the command line, I can investigate what is going wrong.
Thanks in advance,
