Play sound on new messageMore info
When you have an (ANY) open chat, each new comment will trigger a short notification sound. Use this for example when a chat is running on an unattended device. Note that comments will not be updated automatically when the chat window is not active (i.e. not in the foreground of the browser).
Careful, this does not work on iPhones and some browsers, as these prohibit playing a sound without user interaction.
Additionally the screen will flash briefly when a new comment arrives.
