Use this function to query if an audio device is paused.
SDL_bool SDL_IsAudioDevicePaused(SDL_AudioDeviceID dev);
|dev||a device opened by SDL_OpenAudioDevice()|
Returns SDL_TRUE if device is valid and paused, SDL_FALSE otherwise.
Unlike in SDL2, audio devices start in an unpaused state, since an app has to bind a stream before any audio will flow.
Physical devices can not be paused or unpaused, only logical devices created through SDL_OpenAudioDevice() can be. Physical and invalid device IDs will report themselves as unpaused here.
It is safe to call this function from any thread.
This function is available since SDL 3.0.0.
