Any other relevant information or links to logs:
Saving the game, exiting the emulation and restarting it always fixes this issue. The issue seems to come up with small random crackles, then eventually gets to almost all static/crackling when emulation drops below 100% for a split second that seems to trigger the bad crackling after you are 1+ hours in. If the emulation drops below 100% speed before you are 1 hour in, no crackling starts/occurs.
