Youtube streaming goes silent after screen sleep
 

I stream youtube videos in the background using bsplayer free on S5 lollipop.
The screen goes to sleep after 3-5 minutes, and when this happens bsplayer stops playing the audio. I can wake the s5 screen and see BSplayer is playing the video, but there is no audio. I can jog, pause, advance, but I can't get audio back until I close BSplayer and reopen it.

Anyone?
