I don't think that is reasonable.
The first thing most drivers do is reset the hardware. That inevitably leads to some sort of blip, when it comes to sound drivers. If you -don't- reset the hardware, the driver is using hardware that is in an unknown state. (using hardware w/out resetting it == unknown state)
You are depending on the hardware to keep its state -between- driver unload and driver reload. That seems inherently unstable to me. It amazes me that such is supported.
