-/**
- * A variable controlling whether SDL enforces a minimum audio device spec.
- *
- * By default, SDL will require devices to be opened at a minimum spec (at
- * time of writing: 44100Hz, stereo, Sint16 format), so if something lower
- * quality tries to open the device first, it doesn't ruin audio for the next
- * thing that opens a device. For example, if a VoIP library wants Uint8,
- * 8000Hz, mono output, it doesn't force the entire game to this state simply
- * because it got there first.
- *
- * However, an app that knows it will definitely be the only thing opening a
- * device, and wants to open it at a lower spec, might be able to avoid some
- * otherwise-unnecessary conversions by bypassing this minimum requirement.
- *
- * Note that even without the minimum enforcement, the system might choose a
- * different format/channels/frequency than requested by the app; this hint
- * just removes SDL's minimum policy.
- *
- * The variable can be set to the following values:
- *
- * - "0": Audio device mimimum formats _are not_ enforced.
- * - "1": Audio device minimum formats _are_ enforced. (default)
- *
- * This hint should be set before an audio device is opened.
- *
- * \since This hint is available since SDL 3.4.0.
