Refee smart TV Box M6 laggy audio

[DrN0]

I finally managed to get my "Refee smart TV Box M6" (www . refeedigital . com / pro_view . aspx ? id = 67) to work. Video and Audio output is via HDMI. What is not working correctly, is audio output. Playing music from an USB-Stick gets laggy after several minutes, nevertheless if I use Mortplayer, XBMC or inbuild Music Player. After several minutes of correct audio output, the output starts switching on and off constantly. Typically Music progress readings increase while audio output turns on and off.

Does anybody know, how to make audio output stable
