Hi Brian,
Please check your Live Assist settings (even if you aren't using them). You need to set the players there also.

Hi Brian,
The Microphone Mix plugin (which I presume you mean) is designed to be used by users who do not have a desk to plug and XLR microphone into. If you have a deck you should take the output of the desk and use this to broadcast.
Hi Brian,
I'm sorry on Microsoft's behalf about this user interface, it will be replaced in a future update as it is the cause of endless confusion.
Please make sure you click the highlighted blue 'Speakers' text on the dropdown to select the device.
