I've bought and I'm actually really enjoying the HW T650 Soundbar, but when a content is avaiable in Dolby Digital+ I always need to set regular Dolby Digital. I just thought that the soundbar wasn't compatible with it, but I've just read on rtings that it is and they also tested and confirmed its compatibility. I've tried to update the firmware following the instructions on the website but the soundbar won't let me do it. I've tried to change the settings in my Samsung TV but I can't make it work with DD+. I am using HDMI Arc. What should I do?
