[silverblade] 39716: Closing of wave output devices is functional and terminates the sound thread cleanly. Started writing code to support pause/restart (nonfunctional yet.) Stubbed mixer messages, added a readme.txt to give an overview of functions supported. Also includes partial rewrite of wdmaud.drv. Currently I am listening to DI.FM in ReactOS using an NT4 sndblst.sys along with ReactOS' sndblst.dll

Log:
Closing of wave output devices is functional and terminates the sound thread
cleanly. Started writing code to support pause/restart (nonfunctional yet.)
Stubbed mixer messages, added a readme.txt to give an overview of functions
supported. Also includes partial rewrite of wdmaud.drv. Currently I am
listening to DI.FM in ReactOS using an NT4 sndblst.sys along with ReactOS'
sndblst.dll

+MME BUDDY
+
+This library currently is capable of maintaining lists of devices for all of
+the MME types, it will provide the appropriate entrypoints for each device
+type, and code using this library simply needs to inform the MME Buddy
+library of the devices that exist, and provide callback routines to be used
+when opening/closing/playing, etc.
+
+Code using this library needs to provide its own DriverProc entrypoint (this
+may be refactored in future so that simply an init/cleanup routine need be
+provided.)
+
+
+WAVE OUTPUT
+===========
+Supported MME messages:
+* WODM_GETNUMDEVS (Get number of devices)
+* WODM_GETDEVCAPS (Get device capabilities)
+* WODM_OPEN (Open a device, query supported formats)
+* WODM_CLOSE (Close a device)
+* WODM_PREPARE (Prepare a wave header)
+* WODM_UNPREPARE (Unprepare a wave header)
+* WODM_WRITE (Submit a prepared header to be played)
+
+Unsupported MME messages:
+* Any not mentioned above
+
+Notes/Bugs:
+* WHDR_BEGINLOOP and WHDR_ENDLOOP are ignored
+* Not possible to pause/restart playback
