thanks, but these are flac files I converted with ezcd and fre:ac, I checked and there is no protection. They play fine on android and pc etc. Did now test with some other m4a files, and they play fine. Not the ones I convert myself on the r3
Do the files play in their original FLAC format on the R3 (if they do you could try converting them with XLD)? I have found that as per above the DRM protected music from iTunes doesn’t play but as long as it’s DRM free those m4a files play for me on the R3. When I need to convert to other formats I use XLD and haven’t had any issues so far. YMMV.
