(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_HINT_AUDIO_CHANNELS

A variable controlling the default audio channel count.

Header File

Defined in <SDL3/SDL_hints.h>

Syntax

#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.
