Here's my setup. I have two monitors, one with a HDMI port. I plug my Xbox 360 into the HDMI port but since it doesn't have speakers I needed to hook up my computer speakers to it. So I did this: Basically busted open the shell so that the RCA connector will fit into the xbox. Then I plug those connectors, the red and white, into this And I use a female to female adapter to plug in my speakers. However sound only comes out of the left speaker. i plugged headphones in and got the same result. Ideas on why?
