[silverblade] 34534: Corrected wave output device close routine to ensure the device is "idle" rather than "stopped" (which actually means playback is paused...) Also added code to the I/O completion routine to detect when a submitted WAVEHDR from the client application has finished being played. No WAVEHDRs are returned to the client application (yet...)

Corrected wave output device close routine to ensure the device is "idle"
rather than "stopped" (which actually means playback is paused...) Also
added code to the I/O completion routine to detect when a submitted WAVEHDR
from the client application has finished being played. No WAVEHDRs are
returned to the client application (yet...)
