Sound problem with Z1000pro I have some Youtube - demo movies in VP9 HDR format with own music in MP3 underlay. Unfortunately, I have regular sound interruptions of about 5 seconds in irregular intervals. The video continues to run normally without interference. Only the sound stops then. I first suspected the DV10 engine, but it also happens in HDR mode. Could Ziddo please take a closer look? I am also willing to upload my video file somewhere. Greetings hdfan1
