Specify the default ALSA audio device name.
Defined in <SDL3/SDL_hints.h>
#define SDL_HINT_AUDIO_ALSA_DEFAULT_DEVICE "SDL_AUDIO_ALSA_DEFAULT_DEVICE"
This variable is a specific audio device to open when the "default" audio device is used.
This hint will be ignored when opening the default playback device if SDL_HINT_AUDIO_ALSA_DEFAULT_PLAYBACK_DEVICE is set, or when opening the default recording device if SDL_HINT_AUDIO_ALSA_DEFAULT_RECORDING_DEVICE is set.
This hint should be set before an audio device is opened.
This hint is available since SDL 3.1.3.
