thanx for the response:).. i have a simple setup for the sound bar and tv. they are just connected via a HDMI cable.
I use the ARC function if i want to play the tv audio through the sound bar at present. With them both being LG products I do have the SIMPLINK function set to ON..
My problem is if i want to watch a sports channel for example (on mute:), and still play music via ipod, usb etc..from the soundbar, i'm unable to do as i either have to choose an input from the sound bar eg. ipod, usb or tv input eg HDMI 1 which is my input to watch tv channels on a satellite decoder (in South Africa).

thanks again..
