Defined in SDL3/SDL_hints.h

SYNOPSIS

#include "SDL3/SDL.h"

#define SDL_HINT_AUDIO_DEVICE_STREAM_ROLE SDL_AUDIO_DEVICE_STREAM_ROLE"

DESCRIPTION

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/recording 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 , nor an SDL logical audio device.

This hint should be set before an audio device is opened.

AVAILABILITY

This hint is available since SDL 3.2.0.
