The audio glitches and crackles loudly when hibernating as a vampire inside a coffin at 3x speed.

Ideas
Not sure how to edit the post but I need to add that every sim in the household needs to be asleep (or hibernating) for the super speed 3x to trigger the audio issue. It doesn't happen with the standard, slower 3x timescale.
