IDirectSound8::SetSpeakerConfig<br>The SetSpeakerConfig method specifies the speaker configuration of the device.<br><br>HRESULT SetSpeakerConfig(<br> DWORD dwSpeakerConfig<br>);<br>IDirectSound8::GetSpeakerConfig<br>The GetSpeakerConfig method retrieves the speaker configuration.<br><br>HRESULT GetSpeakerConfig(<br> LPDWORD pdwSpeakerConfig<br>);<br>Parameters<br>pdwSpeakerConfig <br>Address of the speaker configuration (see remarks in IDirectSound8::SetSpeakerConfig). <br>The value returned at pdwSpeakerConfig can be a packed DWORD containing both configuration and geometry information. Use the DSSPEAKER_CONFIG and DSSPEAKER_GEOMETRY macros to unpack the DWORD, as in the following example:<br><br> <br> if (DSSPEAKER_CONFIG(dwSpeakerConfig) == DSSPEAKER_STEREO)<br> {<br> if (DSSPEAKER_GEOMETRY(dwSpeakerConfig) ==<br> DSSPEAKER_GEOMETRY_WIDE)<br> {<br> // Configuration is wide stereo.<br> ...}<br> }<br> <br>To use #defines implemented in Windows Vista, set the DIRECTSOUND_VERSION to 0x1000 before including dsound.h.<br><br>
