About two years ago we bought a Samsung TV and the Samsung Sound bar. We had no problem with either until recently. In December 2012, we bought a HUMAX HDR Fox T2 Freeview HD Recorder - 1 TB. Since then, the Humax box has been working on and off, but the sound bar has been affected two. It randomly turns the volume up really high, like very high or else very low. Does anyone have any idea how to fix this? Its really annoying!!
