I see. That's probably due to the audio output on the TV not being controlled by the volume on the TV, but it also might be something that could be set in the TV's menu system. If you haven't checked that already and have questions about it, just let us know what model of TV that you have so that we can look it up. Thanks, I have this TV: Samsung LN40A550 40-Inch 1080p LCD HDTV
