But this thing does not work correctly for me. If I load the page, it says “Sound init failed” and if I test the sound it doesn’t play it (“Unable to play sound!”).

Wuzzy, if you have a GitHub account (or maybe you can do it without one), open an issue at https://github.com/fr1tz/aims-tolservers/issues and paste the messages from the JavaScript console. If you need a GitHub account for that and don't have one, just paste it here.
I had the opposite problem: i was nagged constantly by some strange beep. It took me ages to find out that the pinned tab of that webapp was the source :P
