[WDMAUD_KERNEL]

Browse source 
- Replace mixer / wave support code by mmixer library
[MMIXER]
- Compare device name from 2 character onwards as there are difference in paths in user mode / kernel mode
- Invoke create pin callback if the caller provides it
[WDMAUD.DRV]
- Apply changes from mmixer library

-- Tested in Vbox with Winamp / ReactOS mplay32
