# SDL\_HINT\_AUDIO\_CHANNELS(3)

A variable controlling the default audio channel count.

## NAME

SDL\_HINT\_AUDIO\_CHANNELS - A variable controlling the default audio channel count.

## HEADER FILE

Defined in SDL3/SDL\_hints.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**#define SDL\_HINT\_AUDIO\_CHANNELS** *SDL\_AUDIO\_CHANNELS"*

## DESCRIPTION

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.
