Hello I have the Epson EH-TW 7100 projector, as I want to disconnect from the cable connection, I am switching to the Internet. I have connected the Alexa TV Fiere Stick to HDMI port 1, unfortunately no sound. I connected a soundbar to the projector and a receiver with cable connection via HDMI cable, so I had sound. I no longer need the receiver, the soundbar is still in the projector, the Fiere Stick delivers a picture but no sound. What am I doing wrong? Greetings from Karlsruhe
