[X570 AORUS ULTRA, Nvidia GPU 82 HDMI/DP, Digital Out, HDMI] Underruns, dropouts or crackling sound

[Rim]

I have continuous noise / constant "shooting" instead of the audio and video. I guess it appeared after the latest Ubuntu update. I cannot watch any video, hear any sound in any program, only glitches, shattering noise, and video freezing.
