In the control register, set any bit to be used as output, i.e., whose value is to be controlled by the driver. > Although I can't communicate with DAC.

Does changing the volume here have any effect? BTW: If you're writing code that is intended to be included into OSS, make sure that you actually have all the rights that you're going to assign to 4Front.
