I've been struggling with this issue for a long time now. It happened after a fresh OS install of Windows 10. Basically, as an HTML5 video plays, the audio and the video gradually unsync. The video is also pretty choppy. This does not happen if I force the flash player to be used, so I'm positive at this point it is a software issue.

I tried turning on all the chrome://flags that deal with hardware video decode, as well as turning them all off with no luck. I thought maybe it was my 5.1 receiver and/or TV, but that can't be the case since the flash player works fine (as far as the video/audio not desyncing, but there's other issues with the flash player, like hidden ads playing when playing a YouTube video, but that might be because of the forced flash player hack).

I also tried Canary, but that has the same issue. Firefox and IE have the same issue as well, so maybe this is a webkit issue?

TV is running in 4K, and I've tried a bunch of different refresh rates. The refresh rate seems to change how long it takes to desync. I also have tried to change the audio quality, and when changing it while the video is playing, it resyncs correctly, but then desyncs eventually again.

I've tried to change the audio buffer, but it just causes Chrome to crash it seems, and it seems like that fix is outdated by a few years anyways.

It can't be my machine. It's honestly a beast, and I've posted the configs below. I've updated all the drivers to the ones provided by the manufacturer.  Chrome version 58.0.3029.110; 64-bit of course.
