In the Android 5.1 version is one big issue.
I've got connected Q10 Pro over HDMI to the Denon AVR-X4100W receiver and next to the LG TV.
I'm use MediaCenter at all to play media files (audio and video).
When you play some video file and turn off TV nothing happens, sound is hear further, that's is very good.
When you play AUDIO file via MediaCenter or use YOUTUBE or SPOTIFY and you turn OFF TV, music after a few seconds will stop. On the Roku player and Popcorn Hour player music still plays always after turn off TV.
Can you fix that issue in the new update?
