have a boston acoustics tvee 2 that is hooked up to audio output on panasonic 50" plasma. volume control works 10ft or closer but when further will not work. what it does is learn the volume control code from the panasonic remote so when tv is turned up the tvee soundbar turns up. well when you get further than 10 ft away and try to turn up volume, it won't work, but the tv is receiving the code because it will flash volume up. any ideas here. thanks
