HI My bdv e290 main issue I got at the moment is maintaining the sound when changing the input on tv h. Its been connected to a smart lg tv through the right cables (definitely ) I.e hdmi + optical audio. Most times I change the input .eg dtv, sat, network or smart the sound fails on the dvb though the connection is there as I turn the sound up its been displayed on the tv but no sound comes out. I have changed all the cables just in case but not much luck.somewere must be a setting that I am missing. ..please advise (there are other issues such as noisy fsn and poor display on the set cant see it well if is light in the room)
