I have a Bravia that as far as I can discern from the user guide requires a separate optical digital audio cable plugged into the optical out on my DVI and the PC In on the TV. I bought a cable at Wal-Mart but the plug is too big for the receptacle in the TV. Is there a specific cable I need for this to work?
Maybe you need one of these? fficial&client=firefox-a&um=1&ie=UTF-8&tbm=shop&cid=12430813472282084817&sa=X&ei=ESCDT-XhLIfLgQfRh9X9Bw&ved=0CJsBEPMCMAA" rel="nofollow" target="_blank">http://www.google.com/products/catalog?q=optical+cable&...
Checking the model and manual for the TV would get you more info as to what you need.
I'd also avoid going to a regular store to buy cables, they are always at a huge markup compared to online shops. Even WalMart.
