I have a Marantz 1080P projector with HDMI connections. In order to use the ARC speaker which I bought to provide the sound for my projector, I had to buy a Fury HD Arcana that allows the Marantz HDMI cable to connect to the Fury HDMI-output and then the HDMI cable from the ARC goes to the E-arc output of the Fury. Then if I plug in my Apple TV HDMI cable directly into the Fury HDMI input, I can see the screen. However, when I try to use airplay in Apple TV to mirror my computer onto the projector screen, I have a picture but no sound. How can I get the sound to play from my computer on Sonos. I do have a Sonos connect that I am not using and I am wondering if that could be used in some way to bridge the sound from the computer to the Sonos app.
Also, when I try to connect an HDMI cable from the Fury-input to the 5 port HDR switcher output and then connect the Apple TV’s HDMI cable to the HDR switcher it doesn’t see the Apple TV.
