z9x pro (1.0.65) When I output the sound to my TV via HDMI, there is no problem. However, the problem occurs when the sound is output to an external DAC. When playing 1080P video (DTS, DTS-HD, ATMOS), I occasionally (usually once every 10 minutes or so) hear a popping sound. It's hard to describe exactly, but it sounds like a tick, tick, tick as if the sound is cracking. It gets worse as the movie goes on, about an hour and a half in, and by then it's almost every 30 seconds. And when the movie is over 2 hours long, there is no sound at all. 4K video (DTS, DTS-HD, ATMOS) is even worse. Now I hear the crackling from the first time I run the video, and then after 5 seconds I hear nothing. Does anyone else have this problem or know how to fix it?
