# SDL_HINT_AUDIO_CHANNELS

A variable controlling the default audio channel count.

## 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_CHANNELS "SDL_AUDIO_CHANNELS"
```

## Remarks

If the application doesn't specify the audio channel count when opening the
device, this hint can be used to specify a default channel count that will
be used. This defaults to "1" for recording and "2" for playback devices.

This hint should be set before an audio device is opened.

## Version

This hint is available since SDL 3.1.3.
