Lets get some ideas of other things that need to be fixed or implemented. Sound support is going to be a post 0.3.0 bug for me as I dont have the time or knowlege to try and fix winmm/mmdrv. If you want to see sound on 0.3.0 you need to step up to the plate.
I'd love to work on this, but am still unsure where to begin. I need some sort of sound driver (preferably the VMware one!) that will work with ReactOS, with which I can test.
Alternatively, I need to be able to DBGPRINT out some info from some stub routines in a custom driver...
