Jeff has a Vizio 4K TV with a Bose surround system. He cut the cable recently, but now he doesn't know how to use his surround sound system with the TV because it doesn't have audio out. Leo says most systems now connect audio via a SPDIF or TOSLINK optical connection. The Bose should have an optical connection to it. He'll also need a TOSLINK cable. There's different connectors, so he'll have to see what his Bose wants, and what his TV takes. Monoprice makes them for pretty cheap, and Amazon Basics does as well.
