In that case you would have compiled your assembly routine, known where the address of the volume resides and simply poke a value to it, following that with the routine itself and a Frame Flyback to generate the same effect as if it would have come from the SOUND in basic. The advantage to doing this is perhaps clearer when using other Languages which don't have their own SOUND routines, though can access the Firmware Routines in order to generate the effects using that approach.
