This exclusive mode is not directly available to APIs other than WASAPI. 
However, the audio system might automatically uses exclusive mode if the 
application attempts to use an encoded format (and if the output supports the 
format, and if the Sound control panel settings allow it).

Subject: [wdmaudiodev] Fwd: Exclusive mode in Vista

Dear all,

I have a question about exclusive mode in Vista.

In Vista, audio could be streaming in exclusive mode thru IAudioClient.
Is it the only to use Core Audio API to enable exclusive mode?
Or it could be enabled through higher-level API,
such as DirectSound or even we could enabled it through Directshow audio 
renderer's interface?

I am wondering if exclusive mode could be enabled through IDirectSound's 
SetCooperativeLevel(hwnd, DSSCL_WRITEPRIMARY); ?

Thanks for your kind help.
