I have a sophisti DVD CINEMA SYSTEM. The problem is that when I sets the system to AUX on the panel all the other control units. Keep fluctuating and that the music stops and the cycle continue. When I select say the FM sterio it will play for about a minute and switch to Audio in,then to digital in,to DVD in,USB and at each state takes a minute to reshuffle to the next. It is like the machine automatically reshuffles and does not give a constant tune to any of the available menu.
