My bad, Got it. Thanks for helping out. Yes it does have very high distortion on 200% but It helps when videos have very low sound.

Thanks. It's good now, but rejected because line 6 and 7 (booster.js) should be inside `VolumeBooster._init()` because you cannot create objects in global scope (same as init): https://gjs.guide/extensions/review-guidelines/review-guidelines.html#only-use-init-for-initialization You also used `output = control.get_default_sink();` 3 times in booster.js file. You can create it once in init. Also remove `\n` from description.

1. Can use it with "this" eg. this.control = Volume.getMixerControl() in init? 2. get_default_sink returns null in init so I had to call it every time i use it

1. Yes, that's the correct way. 2. No problem, just call it every time.
