Why does the Clash of Code signal start with sound?

I remember that the Clash of code used to make a few beep sounds when it was about to start. This is no longer the case. Now I sometimes find out late that the clash has already started. Can I turn it on somehow?

Still bips for me. I don’t think there is anyway to deactivate it. Which browser?

I do see lot’s of errors in the console when I enter the lobby for Clash of Code.
