I have a Tivo Roamio. I just upgraded my tv from a 10yo lcd to a new 4k OLED from LG. With it I got a cheap sound bar, because even a cheapo had better sound then the internal speakers. I connected the Tivo to the TV with HDMI and the TV to the sound bar with an Optical wire. Tivo ---hdmi---> TV ----optical---->Soundbar And the sound won't work. All the other devices will put sound out. The blu-ray and the nintendo are connected to the tv in the exact same manner. and they put sound out the out bar. And if I switch the TV to internal speakers, all the devices including the TiVo work. 1) Other device to sound bar: Works 2) Other device to internal speakers: Works 3) Tivo to internal speakers: Works 4) Tivo to Sound bar: DOES NOT WORK What the heck is going on here? Is this some kind of stupid DRM? Is the Tivo buggy?
