Windows 10: PC randomly stutteringfreezing/lagging with buzzing audio

hello!I am experiencing micro stutters or some sort of freezing with a buzzing audio , the buzzing sound isn't from my PC its actually an audio from the system not hardware, actual audio , particularly during gaming but also when using the system for everyday tasks. The stutters appear as random lag, causing a significant disruption in both performance and audio. The issue closely resembles what is shown in this YouTube video: https://youtu.be/qBtwHudKwDA?si=jVD4ETx2nWAkmdhV. Additionally, I am noticing low FPS in games, and these stutters occur intermittently across various applications, no

Continuous audio buzzing but with sound!

My Toshiba had similar problems and I tried every suggestion I could trawl from the net - nothing worked!
My laptop has nVidia/Intel graphics and Realtek sound, and the continual buzz and lag on video was driving me nuts. This was no problem in Windows 7, I even reverted for a while and the issues went away.
Anyway, yesterday I was hunting on the Intel forum and someone mentioned the Intel Display Audio. This is to produce HD sound when the HDMI port is used to connect another device. In my case, it is connecting a Samsung monitor, with NO speakers. I decided to disable the Intel Display Audio in Device Manager (note, disable, not uninstall), and BINGO, buzzing gone, lag gone, stutter gone. I guess plugging-in the monitor told the system to use the Display Audio, but it was conflicting with the Realtek system sound. I really hope this helps someone.
