Constant fermium::hints::SDL_HINT_AUDIO_DEVICE_STREAM_ROLE

pub const SDL_HINT_AUDIO_DEVICE_STREAM_ROLE: &[u8];

Specify an application role for an audio device.

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.
