Just throwing this issue out there to see if any Gurus have some suggestions. I seem to be suffering from a very intermittent issue with video replay on my new rig. I built this 3700x, MSI 450b Mortar, 2070super earlier in the year and opted to go Win 10 Pro for the operating system. For the first few months all seemed well bar having to replace a faulty GPU. A few months ago I started to notice a clear desync between video and audio playback in VLC and an audiable stuttering of audio in Kodi playback. I messed around with a few different options to resolve the issue and seemed to settle with switching my audio source from the onboard Realtek to the GPU audio through my monitor and that seemed to work until recently. So things I have tried, I've tried switching between audio sources, GPU and Realtek onboard. I have also updated GPU and Realtek drivers. I've tweaked in Windows settings changing the audio playback quality as well as adjusting weather programs have exclusive control of audio playback devices. For a few days there I thought I may have nailed the issue as an issue with my media harddrive being the cause however after 3 days of playing videos stored on my NvME back with no obvious issues last night I started to suffer again from visible audio video de-sync during playback. The issue seems to be totally random in nature sometimes occurring after 10 minutes in to a video and sometimes never happening, in all cases closing the playback and restarting the playback software fixes the issue. I've also noticed the issue only once or twice in the past during Youtube playback however there is no issue whatsoever in games. I am honestly at a loss as to what the issue could be.
