The following illustration shows the relationships between DirectSound and other system audio components.
DirectSound and the standard Windows waveform-audio functions provide alternative paths to the waveform-audio portion of the sound hardware. A single device provides access from one path at a time. If a waveform-audio driver has allocated a device, an attempt to allocate that same device by using DirectSound will fail. Similarly, if a DirectSound driver has allocated a device, an attempt to allocate the device by using the waveform-audio driver will fail.
If two sound devices are installed in the system, your application can access each device independently through either DirectSound or the waveform-audio functions.
