The GetConeOutsideVolume method retrieves the volume of the sound outside the outside angle of the sound projection cone.
HRESULT GetConeOutsideVolume( LPLONG plConeOutsideVolume );
Address of a variable that receives the cone outside volume for this buffer.
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
Volume levels are expressed as attenuation, in hundredths of a decibel. Allowable values are between DSBVOLUME_MAX (no attenuation) and DSBVOLUME_MIN (silence). The default value is DS3D_DEFAULTCONEOUTSIDEVOLUME (no attenuation). These values are defined in Dsound.h. DirectSound does not support amplification.
