A:Answer I just had this issue when I set up my new samsung TV. Using the optical, the TV and cable remote volume wasn't working. Had to use the soundbar remote. There was no way I was gonna do that. After messing with it for an hour, I decided to connect the soundbar with the hdmi instead of the optical. I changed the audio setting in the TV back to tv and it worked. All the remotes control the volume now. My old Samsung TV that was 4 years old was able to control the volume while hooked up through the optical, idk why I couldn't figure out the new one. If anyone reading this knows the answer, please let me know. My new TV only has 2 hdmi outlets, so I would like to get the 1 back. (this TV was free through t mobile). My old one has 3 hdmi, but it started getting the white dots, so I need this new one.
