Yeah
Job :D!!!!! Ogg is working fine now in my Meizu M3 (Music Card).
Thanks for you hint, due to that the most perfect DAP I have ever have is complete again!!!
I haven't tried M6 but my M3 do have the best sound of all my devices (I have to confess that I've put some old mp3 albums to listen to them in the M3 to enjoy its sound through my Koss earphones).
Concerning OGG in my humble opinion is the best lossy format, I prefer OGG over MP3 in any bitrate.
Anyway my preferences goes all the time for FLAC, because is a real lossless format (I haven try either WMA lossless yet)
Thanks once again Job
