M300 Optical In Busted?

Hey all, Just got a pair these the other day, trying to hook them up to my TV ( NU6900 Smart 4K UHD TV), and the only sound I get is a buzzing fuzz sound. Fairly certain its not the TV since the board was just replaced about 1 month ago. Unfortunately I don’t have any other optical sources to check with. Thoughts? Maybe I’m just missing something? Thanks in advance.

This might help you out perhaps
