So I've decided to investigate further the stuttering (first 0.5-1 sec of majority of the songs) that I'm experiencing and incorporated
@Vitor Valeri and
@frankraindog 's solutions. Sadly the solutions they had for theirs didn't work for me. This is what I've tested in my case
So the only thing I can conclude for now is it's definitely some kind of combination between SD Card and the Fiio Music app because
1. Never have issues when storing the music files in Internal
2. Never have issues when using a different Music app (used Poweramp and Pi Music Player)
If there's anyone else have experiences with the combination of the Fiio Music App and External SD I would appreciate if you could please share it. Thanks
@FiiO I'm sure you talented folks can easily find a solution for this
