Any way to send split sources audio and video out on HDMI out of OBS?

[michaelagross6119]

I run the soundbooth for our church. I've got HDMI source coming in, as well as audio coming in through the mic port on the cpu. Both are mixed on OBS and we stream to RTMP. I have HDMI out going to a television in another room at our church. I can send video through the preview selection, but how to I send both Audio and Video out on the HDMI port?
