Hopefully someone can help me with this. At the moment if I play a 5.1 movie I only get sound out of the front and centre speakers, nothing from the surrounds. Everything is connected up ok and the amp has the dts/dd lights lit up when the movie plays, just nothing comes out the surrounds. If I set the amp to the multi channel inputs then sound comes out ok (so I know the speakers are connected/setup properly). So what am I doing wrong? I'm assuming the digital connection is ok as the amp correctly recognises the sound format.
