SDL_OpenAudioDevice

Use this function to open a specific audio device.

Syntax

SDL_AudioDeviceID SDL_OpenAudioDevice(const char*          device,
                                      int                  iscapture,
                                      const SDL_AudioSpec* desired,
                                      SDL_AudioSpec*       obtained,
                                      int                  allowed_changes)

Function Parameters

device

a UTF-8 string reported by SDL_GetAudioDeviceName(); see Remarks

iscapture

non-0 to specify a device that has recording capability

desired

the desired audio parameters; see SDL_OpenAudio() for more information

obtained

a pointer to an SDL_AudioSpec structure to be filled in; see SDL_OpenAudio() for more information

allowed_changes

one or more flags OR'd together; see Remarks for details

Return Value

Returns a valid device ID that is >= 2 on success or 0 on failure; call SDL_GetError() for more information.

Code Examples

Remarks

Passing in a device name of NULL requests the most reasonable default (and is equivalent to calling SDL_OpenAudio()). The device name is a UTF-8 string reported by SDL_GetAudioDeviceName(), but some drivers allow arbitrary and driver-specific strings, such as a hostname/IP address for a remote audio server, or a filename in the diskaudio driver.

allowed_changes can have the following values:

SDL_AUDIO_ALLOW_FREQUENCY_CHANGE

SDL_AUDIO_ALLOW_FORMAT_CHANGE

SDL_AUDIO_ALLOW_CHANNELS_CHANGE

SDL_AUDIO_ALLOW_ANY_CHANGE

SDL_OpenAudio(), unlike this function, always acts on device ID 1.
