My LG TV also lost external audio connectivity, model is 55LF6100-UA. It used to work when I connected it to an amplifier but it stopped. Any help is greatly apreciated.

Check the TV audio menu to make sure that the audio output is set as it was.
Make sure that your amp is on the correct input.

Thanks for your answer. I have already checked those two items you mention. It used to work before, a couple of months ago but now it just doesn't. I have also checked the optical cable. Is there anything else I need to check?
