Re: (iOS)Why use AudioQueue instead of AudioUnit

I think SDL_PauseAudioDevice() can not achieve this purpose.

Even if the play is paused, SDL will still call AudioQueueEnqueueBuffer,
just to set desired data to 0.

By the way, I implemented to "Pause" based on AudioQueue. Below is code.
-----------------------------------
static void COREAUDIO_PauseDevice(_THIS, int pause_on)
{
	if (pause_on) {
		AudioQueueStop(this->hidden->audioQueue, 1);
	} else {
		OSStatus result = AudioQueueStart(this->hidden->audioQueue,
NULL);
	}
}

Is SDL_PauseAudioDevice() not an option?

Talking directly to system APIs for stuff SDL is handling for you tends to
be dangerous, for just this reason.
