I went through the menu and could not find any kind of volume limiter, a couple things I don't understand but tried all the options and nothing seems to help. In our ACE 30.1 this is the TV over the kitchen counter that swings out so am not sure where the sound bar would fit. It is also a bit annoying to think we would have to do this to make up for an inferior OEM part. OTOH we are very happy with our ACE and plan to make it a long term member of the household. Jim.
