Making an extension that plays audio even when the extension is closed

[Larrie]

I'm making a simple extension that loads an HTML file as the default popup.

In the HTML file I have an <audio> element.

In the <audio> element I am linking to a javascript file that loads a .pls file.

When I open the extension the audio plays fine, but when I close the extension or switch tabs the audio stops playing.

Is there a way so when I close the extension or switch tabs the audio will keep playing?

Is it even possible to have popup.html playing audio when the extension is closed?

popup.html

manifest.json

I tried adding audio-player.js as a background service worker in my manifest.json file and I also tried adding popup.html as a background service worker:

And

But the audio stops playing when I close the extension.

Any help much appreciated.

Thanks.

There's no sensible solution in ManifestV3 until chrome.offscreen is implemented in stable Chrome, currently it's still in development/Canary channel. Either use a ManifestV2 extension for now or open a new small window which will play the audio (you can open it in a minimized state).
