/**
* \brief A variable that causes SDL to not ignore audio "monitors"
*
* This is currently only used for PulseAudio and ignored elsewhere.
*
* By default, SDL ignores audio devices that aren't associated with physical
* hardware. Changing this hint to "1" will expose anything SDL sees that
* appears to be an audio source or sink. This will add "devices" to the list
* that the user probably doesn't want or need, but it can be useful in
* scenarios where you want to hook up SDL to some sort of virtual device,
* etc.
*
* The default value is "0". This hint must be set before SDL_Init().
*
* This hint is available since SDL 2.0.16. Before then, virtual devices are
* always ignored.
