Timer/counter 4 is enabled on Arduino init() and a Timer/counter 4 overflow may happen right after the timer/counter 4 interrupt is enabled. When this happens the channels have not been initialized yet causing random noise/sounds being played.
This has been fixed by moving the interrupt enable after the channels have been initialized.
