###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_HINT_AUDIO_DEVICE_STREAM_ROLE Specify an application role for an audio device. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_hints.h) ## Syntax ```c #define SDL_HINT_AUDIO_DEVICE_STREAM_ROLE "SDL_AUDIO_DEVICE_STREAM_ROLE" ``` ## Remarks Some audio backends (such as Pipewire) allow you to describe the role of your audio stream. Among other things, this description might show up in a system control panel or software for displaying and manipulating media playback/capture graphs. This hints lets you transmit that information to the OS. The contents of this hint are used while opening an audio device. You should use a string that describes your what your program is playing (Game, Music, Movie, etc...). Setting this to "" or leaving it unset will have SDL use a reasonable default: "Game" or something similar. Note that while this talks about audio streams, this is an OS-level concept, so it applies to a physical audio device in this case, and not an [SDL_AudioStream](SDL_AudioStream), nor an SDL logical audio device. This hint should be set before an audio device is opened. ## Version This hint is available since SDL 3.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryHints](CategoryHints)
