Sorry if this has already been posted but I did a search and a few are close, but not quite the same setup. I recently decided to set my surround sound back up. I bought a set of Klipsch Quintet speakers (which I love) to hook up to my Onkyo HT-R340 receiver. Not the most extravagant system, but its fine for me.
My current connection setup is I have my Xbox connected to my TV (LG 55LW5600) through HDMI. I then have an optical cable connecting my TV to my receiver. I realize that with some TVs, the audio is compressed to 2 channels when passed through. This is not the case. I have been able to get 5.1 from my PS3 with the same setup. I have set the Xbox to output 5.1 in the menu. I tested known 5.1 sources with the Xbox and just can't seem to get anything other than 2.1. Is it possible to get 5.1 from the Xbox with this setup?
Thanks in advance.
