Looking for co-maintainer - contact beejeebus if you're interested!
This module enables chat rooms to be set up on Drupal sites.
6.x-2.x is stable, but doesn't scale well.
7.x-2.x is stable, and scales well by using the Node.js integration module..
To enable sounds with Chatroom, check out the Chatroom sounds module.
8.x-1.x is alive! Thanks Võ Xuân Tiến.
