Audio following wireless HDMI signal

Back again, trying to get a secondary worship space configured for my church. We are currently streaming with three cameras into a Blackmagic ATEM Mini using an Actiontec MyWirelessTV2 transmitter for each. I have a sound board running into the ATEM Mini via the Mic #1 input, and then OBS to stream. We are adding a projector in a second room as a live program feed for more people.

The projector has another Actiontec MyWirelessTV2 (4 total) picking up the signal from our streaming computer. We are running a Zotac GeForce GT 730 graphics card for the two monitors and the projector. I have a second window for the program projector working. I have a set of speakers plugged into the computer to playback imbed videos while streaming. I cannot get the projector to pick up the audio that should follow over HDMI. Could it be as simple as audio selection on the computer or can someone steer me in the right direction?
