Can you please share the HDMI settings of your Jio STB and the TV? I also have Jio STB and a 9 year old Yamaha home theatre setup. I cannot get HDR from Jio STB and surround sound working as expected. While Dolby Vision and surround sound works fine with the TV Native Netflix app, however with Jio STB, the TV shows HDR instead of Dolby Vision and no surround sound. With native Amazon Prime, the HDR and surround sound works as expected however, with Jio STB there's no sound from home theatre. I've connected AVR to TV's HDMI ARC port and Jio STB to one of the remaining HDMI ports of the TV.Yup, even my Jio Box displays exactly same as native TV app. Zero difference but better motion and upscaling.
