OK, I've recently gotten a turtle beach headset and I'm having some troubled getting it to work. I have an HDMI setup and from what I understand from the directions I don't need the adapter if my tv has the AV audio out (which it does). I also made sure that under my preference settings the sound comes out of my headset (which it is) I have tried EVERYTHING. I even switch back to the a/v cables and it still didn't work. I know nothings wrong with the head set because it works fine on my laptop. Any suggestions?
