- Start implementing a mixer library. The mixer library is based directly on the code in
the wdmaud driver. The purpose is to provide a generic library which can be used in
usermode (wdmaud.drv (Vista Driver Model)/ dsound) or in kernel mode. In addition, it can
be used to test mixer implementation.
