It does both. start is from the base class Thread, it starts it which immediately opens the audio device and can feed stuff when it is necessary.

It's not performant or complete by any means, just a minimal example in D like you wanted. You probably also want methods for removing nodes or inserting in the middle (else why don't you use an array?), I think you can think of an implementation for those yourself (or look them up, there should be plenty examples online). https://tutuapp.uno/ , https://9apps.ooo/ , https://showbox.kim/

You need to stop before joining otherwise join may never return. Alright, thanks. So let me see if I get this straight, .stop() will stop the thread and then .join() will return. But what exactly does .join() return?

Can anyone just please show me how to play a background
sound(like those in games) using arsd.simpleaudio? I'd like
something simple with a code snippet please.
it is really minimal be warned
but at the beginning of main() set it up with
auto audio = new AudioPcmOutThread();
audio.start();
scope(exit) {
audio.stop();
audio.join();
}
and then when you want it to make sounds, call its functions
like
audio.beep();
or
audio.playOgg("my-file.ogg");
you can convert things like wav and mp3 into the ogg format
with various tools of the internet.
that's about all it does.
Are you sure it is like this:
audio.stop();
audio.join();
and not like this:
audio.join();
audio.stop();
?

It shouldn't really matter (at least not with the newer versions) since it will automatically exit the audio thread when the main thread exits, but still there's definitely no benefit to writing it without the scope guard. I'm very minimalistic, I hate unnecessary complexity, I believe that simple is better than complex so I always try to use the least syntax and lines of code when I'm making a program. That is why I don't like the scope guard. Could I simply add the lines `audio.stop(); audio.join();` to the very end of main()?

I tried reading up on dub, but got lost in the docs, so I really don't understand what all it can do. Dub is a tool for developers, I understand your requirements that you want target end customers of your applications. Therefore dub is the wrong tool for this job. To be more precise, gtkd is a wrapper for GTK. Gtkd is not interesting in this context, but the dependency on gtk. On windows you have the possibility to either publish your application with GTK dlls or to run gtk setup routine as part of your application setup routine or just say in your readme that the customer needs to run GTK setup on there own. On posix (linus, macos) of course you can also say in your readme that the customer should run apt-get ... to install gtk (here I do not have much knowledge on packaging). Kind regards Andre I will immediately abandon any app that provides this sort of incomplete experience to use unless I have my developer hats on...or I really have not other choice.
