I was having significant issues with the unit recognizing my SD card. Come to find out that there was a corrupt file loaded onto the internal memory. Was taking too long to discover what it was (sifting through 64g of music is hard) so I re-formatted the internal drive and reloaded about half of what I had there and slowly began to rebuild my files. I was doing it slowly as to rescan after say 50 or so files were loaded to see if I could find the culprit. The unit appears to work more swiftly now and I now can see all the files (internally and on the card) without issues. I think this operating system is a lot less forgiving on what files are used. I am not sure what was corrupted but I do not have any issues with Fiio or Apple units behaving this way with the same files (except for FLAC on the Apple). My 100ii was also experiencing the same problems until I re-formatted that as well. Now I have both AK units performing well.
