NAME
SDL_HINT_AUDIO_INCLUDE_MONITORS - A variable that causes SDL to not ignore audio "monitors".
SYNOPSIS
#include <SDL3/SDL_hints.h>
#define SDL_HINT_AUDIO_INCLUDE_MONITORS "SDL_AUDIO_INCLUDE_MONITORS"
DESCRIPTION
This is currently only used by the PulseAudio driver.
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 variable can be set to the following values:
• "0": Audio monitor devices will be ignored. (default)
• "1": Audio monitor devices will show up in the device list.
This hint should be set before SDL is initialized.
AVAILABILITY
This hint is available since SDL 3.2.0.
