High GPU usage causing audio to cuts off

First sorry if I post in the wrong section, since it's either graphic card or sound card.

The problem as title says, whenever GPU usage hits high usage (90-100%) when playing games it will cut off the audio. I took some video of it from witcher 3 gameplay with vsync off => YouTube

As for normal use like browsing the net, watching youtube, watching movie, etc works just fine.

Things that I observe that any apps that cause high gpu usage will cause the same things or causing realtek plug/unplugged notification went crazy, like running userbenchmark (only at gpu test), 3dmark, unigine, etc.

Any idea where might be the cause? Just for reference I never had a problem with the system circa 2017-2018, most of issue appear in mid 2019 circa windows 10 build 1809/1903 update.

I assume that the Nvidia drivers are up to date? As well as the Realtek drivers? It may seem obvious, but that is a good place to start.
