- Enable mmixer library in wdmaud.drv
- Delete unused code
- Don't call wave streaming handler again from the io completion callback. As this will sooner or later will cause crash because the stack got eaten
- Create a thread for each io packet and handle the completion callback within it.
- Audio packets are now directly routed from winmm -> wdmaud.drv -> portcls instead of winmm -> wdmaud.drv -> wdmaud.sys -> sysaudio.sys -> kmixer.sys -> portcls.sys
- Needs more testing & fine tuning, to fixup audio glitches
