About the problem:
I’ve installed volumio v1.55 at my raspberry pi 2 and it works verry well, but i want to play music with the “trow function” of my sony xperia z3 compact and there are some problems.
Some music doesn’t work with throw, but the same track on USB works. And it get stuck sometimes when i change the track manualy.
Otherwise playing music from the USB stick works without any problems, it just fails with my mobile phone.
Thanks for your help in advance.
