How does the optic audio input work?

Asked by: dgargaro
Hi dgargaro. We are not clear on your inquiry with regards to "How does the optic audio input work?". The LG 4K UHD HDR Smart LED TV - 49" Class (48.5" Diag), Model # 49UJ6300 does not have an Optical Digital Audio Input, it has an Output that sends out an uncompressed 5.1 digital signal. You will need an optical cable (also referred to as a Toslink cable) to connect it to the Optical Digital Audio Input of a compatible receiver, Sound Bar or HomeTheater System. In the TVs Menu settings, you can navigate to 'Sound" and specify the audio path that you would like the TV's audio to be output through...^IFV
