DirecTV set up through a J-tech audio extractor
I have a theater set up with a Sony 4K projector and a Sonos-Arc sound bar. Source material (like Netflix via internet or a DVD player) goes through a J-tech (JTD18G-H5CH) audio extractor to the sound bar and projector and works great. The coax that feeds the extractor comes from a MSPLIT8R1-03 DirecTV SWM. My DirecTV DVR (HR54-500) will work if connected to the red-center out on the SWM (there is only one of these). For any other out port, the video comes through the extractor to the projector fine, but there is no sound whatsoever. I would like to have my DirecTV mini (C51-700) be the DirecTV source so I can keep my DVR on a different floor, but when I hook up the mini it shows only video and no sound whatsoever no matter what SWM port I attach it to (even the red; all other out ports have yellow centers). Is there an output sound compatibility that the DVR has that is not passed on to the minis (like an EDID format)? Can I split a coax signal at some point to use a mini with my theater set up?
