When I upgraded my PC to the same CPU, I had the same problem of crackling/buzzing speakers on my USB DAC (externally powered, but from the same strip/outlet) when the system was under load.

I had a hunch it was power related because my PSU was nearly 10 years old and probably with just barely enough wattage. I bought a new one and all the buzzing went away.

IIRC when I was researching possible causes, beefy Ryzen CPUs were the most commonly mentioned in various forums and reddit threads.
