// @flag DSSCL_NORMAL|Sets the application to a fully cooperative status. Most applications should use this level, because it has the smoothest multitasking and resource-sharing behavior.
// @flag DSSCL_PRIORITY|Sets the application to the priority level. Applications with this cooperative level can call the DirectSoundBuffer.setFormat and DirectSound.compact methods.
// @flag DSSCL_EXCLUSIVE|Sets the application to the exclusive level. When it has the input focus, the application will be the only one audible (sounds from applications with the DSBCAPS_GLOBALFOCUS flag set will be muted). With this level, it also has all the privileges of the DSSCL_PRIORITY level. DirectSound will restore the hardware format, as specified by the most recent call to the DirectSoundBuffer.setFormat method, once the application gains the input focus.
