You might notice that the non-streaming Javascript interface in the Demo site is beeping. We're testing audio alerting, and soon will add configuration options to the login page. If your chat window is hidden, having it make a sound can alert you that something is happening there.

At present, there is one beep sounded every time at least one message appears. If several messages are displayed at the same time, only one beep will sound.

We plan to allow the site Administrator to control whether sound is enabled, and each user will be able to turn off the sound.
