Anyways... My question is, if I hook up a set of speakers (2.1 speakers with a subwoofer) through the optical audio out on the back of the TV, will Clear Voice still function? Or does it require you use the speakers that came with the TV?
I have a LG TV too, in that TV you can select what kind of output goes through Optical or analogue audio out.
If you select "Monitor Out", this will send audio without any processing. I.e. without applying clear voice.
If you turn that off, Audio output would be processed audio, and will have clear voice applied to it.
