Advertisements I have the Tivo plugged into an HDMI Audio Extractor. The Extractor is connected to my TV via an HDMI cable, and my A/V receiver via an optical cable. As you can see in the attached photo, the setup turned on the Dolby Digital and DTS settings, my receiver shows it's getting Dolby Digital 5.1 (3/2), and all 5 speakers and sub woofer are active. I've tried several HBOmax movies including WW84, but I only get stereo sound from the the Right and Left speakers. No sound from any of the others. Help!
