Specify an application name for an audio device.
Defined in SDL_hints.h
#define SDL_HINT_AUDIO_DEVICE_STREAM_NAME "SDL_AUDIO_DEVICE_STREAM_NAME"Some audio backends (such as PulseAudio) allow you to describe your audio stream. Among other things, this description might show up in a system control panel that lets the user adjust the volume on specific audio streams instead of using one giant master volume slider.
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 ("audio stream" is probably sufficient in many cases, but this could be useful for something like "team chat" if you have a headset playing VoIP audio separately).
Setting this to "" or leaving it unset will have SDL use a reasonable default: "audio stream" or something similar.
On targets where this is not supported, this hint does nothing.
