Why when Gameboy or NES games glitch, there is often a buzzing or “screeching” sound?

Question

I heard it was that it is trying to read non sound bytes as sound, but im not sure how accurate that is.

Answer 1

If you mean that repeating sound that won’t stop until the glitch is resolved that’s usually because the sound that was playing when it happened gets stuck in a loop.
