Hey guys,
Been playing with the M3 for about a week now... There are solutions to some of the issues mentioned here and seems unfortunate that FiiO hasn't responded officially.
Regarding tracks being listed/played out of order, this seems to be an issue with filenames that have a space in them before the numbers. In parallel to this, if you ensure your number is always ## this issue doesn't seem to happen.
For example..
"1 - Test"
"10 - Test"
"2 - Test"
can be fixed by doing:
"01 - Test"
"02 - Test"
"10 - Test".
Likewise...
"Awesome Album - 01 - Track Stuff"
"Awesome Album - 10 - Track Stuff"
"Awesome Album - 02 - Track Stuff"
can be fixed by doing:
"01 - Awesome Album - Track Stuff"
"02 - Awesome Album - Track Stuff"
"10 - Awesome Album - Track Stuff"
I know the above is a pain, but it seems to work for me in all cases.
Regarding SD Card tracks not showing up in the Audio Library, this happened for me when I formatted my SD card on a PC and then loaded it on a PC with my SD card reader. To fix, I formatted the external storage (back your files up first) from within the M3 settings menu, and then transferred all my tracks back onto the M3 via the USB cable. After transfer was complete, all my audio from both internal 8gb and external MicroSD card show up within the library and are present in the songs/artists/albums listings.
Hope these workarounds help you guys!
Cheers,
Levi
