SDL_GetAudioPlaybackDevices

Get a list of currently-connected audio playback devices.

Header File

Syntax

SDL_AudioDeviceID * SDL_GetAudioPlaybackDevices(int *count);

Function Parameters

int *

count

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

Return Value

(SDL_AudioDeviceID *) 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.

Remarks

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.

Thread Safety

It is safe to call this function from any thread.

Version

This function is available since SDL 3.1.3.
