my stored library is appr. 3.900 albums - mostly mp3 encoded but all my audiobooks (lots of them for my kids) are all m4b encoded. Volumio is unable to play these m4b-files! Or to be more precise: volumio recognize the files with all their information in tags and plays them well - but with no sound! Not a single tone! Total silence!
Does anybody know why? And much more important: what´s the solution?
