Hi,
I have (I believe) the same problem watching YouTube videos, not specific ones, just all of them generally. After some time the audio gets ahead of the video bit by bit. The delay grows slowly over time, so I don't really notice as it's happening until the audio is seconds ahead of the video.
Version: 44.0.2510.1449 (PGO)
Update stream: Stable
System: Windows 10 64-bit
Extensions: LastPass, uBlock Origin (disabled for YouTube)
Over the next few days I'll try disabling antivirus, vpn, extensions etc. to test if something specific is causing it and update with results.
