Quit audio before application exits.

In my application, I have audio running thrughout the whole time the application is open.

However, whenever I exit the application, my computer makes a noise that makes me think that something went wrong. I dont really know how to explain it other than it is just one tone and it does not sound like the audio that I had playing.

Is there a way to make this sound not occur? Should I stop the audio from playing before the application exits?

How are you playing the audio?

I don't know how your application is exited, but unless you call System.exit, the sound playing threads will continue until they end. I'd definitely stop them. Also, you should make the playing variable volatile, as it's clearly meant to be shared among multiple threads.

I don't see any GUI related code here, so I'll move this thread to Java in General.

I use system.exit(0) to exit the program when the x button is pressed. (and I changed playing to volatile) But it still makes the sound.

I have now added this line to my code, and it runs right before the program exits.

However, it makes a very... very loud annoying sound that scares the crap out of me. And even after the program has exited, it will repeat the sound a few times after when you try to play any audio.

Heres the code:



It is in the Sound.class as seen in the code in my second post.

Now I have edited that code to this:



It does not have a sharp sound anymore, but it still makes the noise that I started out with. Just for a shorter time period.

How could I stop the noise from occurring completely?

How about:

That loop just controls whether to loop or not. The nested loops are the ones that play the audio.

Yes, but each time through the loop you call line.start() and line.close().
