I have the Vero 4K+ connected via HDMI to a Pioneer VSX-1020 AVR and I’m using pass-through (all audio settings below). The receiver is set to Pure Direct, but I’ve had the same results when it’s set to Auto Surround. I’m having issues with both DTS-HD MA and TrueHD.
I’ve tried 2 different HDMI cables. I have tried all 3 Output Configurations. Best Match and Optimized will sometimes give me HD audio, but sometimes it won’t. If it does and I hit pause, I may get no audio when I resume or I may continue getting HD audio. Fixed gives me working audio using PCM Direct, as my AVR calls it, but it often starts out at extremely low volume. If I pause and resume, the audio volume returns to “normal”.
For the debug, I played the same file using Best Match, then Optimized, then Fixed. For the first two, I paused and resumed until I acheived DTS-HD MA and then lost it. For Fixed, I just paused and resumed a few times; audio began low, but after pausing, returned to “normal” level.
