I have this issue too and it is darned annoying. In fact, if this cannot be solved it may be the final issue that makes me return the damned thing. I listen to music a lot in the car by patching the headphone out to the aux in of my stereo.
For me, most often will plug in audio and get nothing at all from the stereo even though it's plugged in. Then for some reason maybe on the fifth or fifteenth try the audio will finally come through the stereo.
Also whenever the player changes tracks, between songs, not only is it not gapless, but there's a loud "spark" noise. HIGHLY annoying. My old Samsung and my HTC M8 never did this.
