I recently reorganized the cords and hookups behind my TV. I have an optical cable connecting my Samsung surround sound receiver to my Samsung TV. I've always had it hooked up this way and it's worked as expected with sound for all connected devices coming through the surround sound. However, after plugging everything back in, sound doesn't come through the center speaker and instead comes through the TV. So basically my TV is now acting like my center speaker with the other surround speakers working as expected. I know theres probably some setting messed up somewhere but would greatly appreciate the help if someone could point me in the right direction.
