- Fix a bug in KsAllocateDeviceHeader which copied the create item to the wrong offset
- Set Created status to true when create function is not zero - Partly implement KsStreamIo - Implement IOCTL for opening / setting state and writing wave data - Clear KSAUDIO_DEVICE_ENTRY - Open the pin in a worker context as IoCreateFile must be called at APC_LEVEL < - Add dispatcher object to sysaudio will dispatch the device requests to the real pin - Add a test application to play a wav sound - ReactOS can now play a wave tone svn path=/trunk/; revision=39702
