Purchased the TV and Soundbar (Samsung HW-Q700C/ZC 320-Watt 3.1.2 Channel Sound Bar with Wireless Subwoofer). Connected through optical cable (TV Sound + Soundbar (Optical)) and had no issues, okay sound. Sometimes would get a lip sync issue and needed to change source and go back to same source for the sync to correct itself. However I noticed a couple of nights ago that this option no longer exist and I have to use TV Sound + Soundbar (WiFi).
The optical cable is brand new and still works because I have an option under sound for Receiver (Optical) and if I do this the sound will come out the the soundbar. I can choose the soundbar (wifi) connection and sound will come out of the soundbar too.
Reset the sound setting on the TV but that did nothing. Stumped as to why I lost the "TV Sound + Soundbar (Optical)" option. I really don't want to have to reset the soundbar or TV (more so cause I had it tuned) but seems like my only option
