SDL_HINT_AUDIO_CHANNELS - Man Page

Defined in SDL3/SDL_hints.h

#include "SDL3/SDL.h"

#define SDL_HINT_AUDIO_CHANNELS SDL_AUDIO_CHANNELS"

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.

This hint is available since SDL 3.2.0.
