###### (This is the legacy documentation for SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) # SDL_HINT_AUDIO_DEVICE_STREAM_ROLE Specify an application role for an audio device. ## Header File Defined in [SDL_hints.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/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. On targets where this is not supported, this hint does nothing. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryHints](CategoryHints)
