Crash in Playing

[harryworld]

Any idea on what's happening?

For some reasons, we implement our code like this.

            DispatchQueue(label: "com.staysorted.soundfx").async {
                Sound.play(file: sound.filename)
            }

Hi Harry,

Thanks for raising the issue.

Unfortunately, I am not able to reproduce it.

The only thing that I can think of is the following.

Try to create the dispatch queue and store a reference somewhere:

let queue = DispatchQueue(label: "com.staysorted.soundfx")

And then use the queue to play sounds:

queue.async {
    Sound.play(file: sound.filename)
}

Please let me know if you are able to give some tips on how to reproduce the issue and if my proposed solution works.

Thanks for response @adamcichy
We don't have a clue either, it's just quite random and frequent in our use case.
We just removed the async wrapper, and going to test out in new release.
Will come back on this.

@harryworld Have you experienced the crash since your last post? Have you got more details that could help identify the issue?

[harryworld]

It's working fine so far. We have followed your suggestion above.
Thanks.

That's great. Closing the issue.
