# SDL_HINT_AUDIO_DRIVER

A variable that specifies an audio backend to use.

## Header File

Defined in [<SDL3/SDL_hints.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_hints.h)

## Syntax

```c
#define SDL_HINT_AUDIO_DRIVER "SDL_AUDIO_DRIVER"
```

## Remarks

By default, SDL will try all available audio backends in a reasonable order
until it finds one that can work, but this hint allows the app or user to
force a specific driver, such as "pipewire" if, say, you are on PulseAudio
but want to try talking to the lower level instead.

This hint should be set before SDL is initialized.

## Version

This hint is available since SDL 3.2.0.
