That's just not up to you.  When the audio system was totally redesigned in Vista, they changed the philosophy.  The audio ecosystem prior to that had become the Wild Wild West, with clever vendor after clever vendor inserting "helpful" filters and customizations into the audio stack.  The result was that the high-end professional audio application companies started to complain that they couldn't achieve reproducible results from system to system.

So, in the redesign, the application and the user are in charge. The driver and any APOs are merely slaves.  You don't get to make policy decisions.
