Let's see that lg.com link to the manual that shows this feature. Almost all models don't allow this due to inherent audio delays. When they allowed this, the consumers complained about the audio sync. So for now, all models seem to allow one or the other.
I am attempting to setup my audio headphones to my LG TV's digital optical port. I have connected the optical cable to my 3.5mm cable with an adapter. I am trying to set this up so sound will simultaneously come out of the TV's internal speakers and through the headset. I have set my UH6350 TV's Sound Out setting to the setting that allows for the internal speaker and audio out at the same time using the optical port. No sound is coming through the headset. Do I need something else to make this work?
Thank you in advance
