If set, direct DAC output commands are instantaneous.
This option is intended as a quick fix for games or demos that play direct DAC music/sound from the IRQ 0 timer who a) write the DSP command and data without polling the DSP to ensure it's ready or b) can get locked into the IRQ 0 handler waiting for DSP status when instructed to play at or beyond the DSP's maximum direct DAC sample rate.

This fix allows broken Sound Blaster code to work and should not be enabled unless necessary.
