He implemented it by pulling the Audio In pin of the SID low(ish) using a resistor (see http://solder.dyndns.info/pub/files/commodore/plus4/hardware/SID-Card/Schematic_SID-card.gif). That puts a constant voltage level on the mixer... he might have taken that hack from C64 where it had been a problem that "new" C64s (8580) didn't play digi for long (they had already invented that method by then).
