I purchased a pair of headphones that use optical out for surround sound. However, I have the optical out on my 360 Slim connected to a receiver and would prefer not to have to plug and unplug it to use the headphones. I do have an official audio adapter with RCA and optical connections from an older model 360 that needed it. I was wondering if it's possible to connect the adapter optical connection to my headphones and regular optical out to my receiver. Thanks!
