Im looking into getting the Yamaha - 5.1-Ch. Home Theater System with Subwoofer. Ive never had or hooked up a home theatre and not sure if it comes with the cables to hook up to my olevia tv. Im not sure what exact tv it is but its olevia. I have a HDMI cable but I am using it with my xbox. Dose this system come with the cables i need to hook up to my tv??? Any help or tips on how to set up please help! Thanks.
