There's actually 2 related problems here..
We have various groups (sales, billing, etc). We have all agents as members of all groups, so that they can see tickts in all queues and not only for their primary department.
For live chat, we have disabled the live chat options for agents who are not primary to that particular group (the billing agents have live chat disabled for their user in the sales department)
However, EVERYONE hears the live chat sounds regardless of these settings (a new live chat in the queue, idle warning sounds)
This has to be a bug, since the agents hearing sounds are not even enabled for live chat in the department.
Furthermore, the SECOND bug regarding this is that the agents who aren't even signed into live chats still hear sounds (ie - when logging into SmarterTrack, or verifying through the 'Active Groups' - these agents have NO checkboxes enabled under ANY of the live chat groups), yet they hear all the live chat notification sounds/warnings.
We're currently on SmarterTrack 10.5 and will be doing the minor upgrade shortly but I don't believe this is something that is listed in the bug fixes so assuming it will still be an issue after upgrading as well.
