I select the "speaker enhance"and "surround music" options to on and set the sub woofer setting to #3 to watch a program. When I change channel's it turns off the speaker enhance and the surround music and sends the sub woofer back to #2. Is there a way to lock these in and keep them from moving each time I change the channel. I bought a Logitech HARMONY 659 thinking I would be able to program it with this. It doesn't seem to have an option either. Any suggestions?
