I've been using the Go since it's release and have had smooth playback in the Video player and now the Gallery up until recently. All files have been 4k .MKV exports, previously only issue is the 5 frame sync which has been well documented. Now all these videos playback with constant audio glitches. I am exporting a project for a client and this is of major concern. I've tried restarting the Go to no avail. Current Version 3.51.56 runtime version 3.4.11. Encoding with FB 360 Spatial Workstation according to specs that are also well documented.
