SDL_GetAudioPlaybackDevices - Man Page

#include <SDL3/SDL_audio.h>

SDL_AudioDeviceID * SDL_GetAudioPlaybackDevices(int *count);

This returns of list of available devices that play sound, perhaps to speakers or headphones ("playback" devices). If you want devices that record audio, like a microphone ("recording" devices), use SDL_GetAudioRecordingDevices() instead.

This only returns a list of physical devices; it will not have any device IDs returned by SDL_OpenAudioDevice().

If this function returns NULL, to signify an error, *count will be set to zero.

count

a pointer filled in with the number of devices returned, may be NULL.

Returns a 0 terminated array of device instance IDs or NULL on error; call SDL_GetError() for more information. This should be freed with SDL_free() when it is no longer needed.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
