Name of audio cable that hooks up to my lcd tv? - white small lcd tv

My friend only to connect to my computer to my LCD TV.
I think that with outstanding audio performance of others through my Bose receiver. I think I know which hook the PC to the shared TV, a small hole into a single "helmet" style of Jack audio cable is available in red and white. What are these cables called? Thank you!

In fact, I have connected the TV via RGB cable for PC.
