/* MS docs:
*
* When there are no sounds playing, DirectSound stops the mixer engine and halts DMA
* (direct memory access) activity. If your application has frequent short intervals of
* silence, the overhead of starting and stopping the mixer each time a sound is played
* may be worse than the DMA overhead if you kept the mixer active. Also, some sound
* hardware or drivers may produce unwanted audible artifacts from frequent starting and
* stopping of playback. If your application is playing audio almost continuously with only
* short breaks of silence, you can force the mixer engine to remain active by calling the
* IDirectSoundBuffer::Play method for the primary buffer. The mixer will continue to run
* silently.
*
* However, I just added the above code and I don't want to change more until it's tested.
