Try one of these, nothing much to loose, £4.99 delivered!!! I have a CYP DAC that does the same job for much more money if you want to try it..... To be honest this DAC on ebay has been said to be all you will ever need if you give it a good linear supply, this was by someone who has been building hi end gear for about 40 years, no need for that on your TV, just plug the USB cable into one of the TV's USB sockets and job done, the cables supplied will cost you more than the DAC! I bought 2, no complaints. https://www.ebay.co.uk/itm/Optical-D...item5468bfb4e8
