I recently purchased 'PHILIPS DSP56U' 5.l multimedia system and got it connected with my laptop. All the speakers are connected good and all the channels responded well for the test sounds. The stereo music tracks and other normal movies (stereo) plays good. I'm having a problem with playing a movie with a 5.1 audio track. I can hear the background soundtrack, weapon effects, but I cannot hear the dialogues (which I assume to be a separate track). I'm using VLC to play the movie and it would be grateful if someone help me through this :)
One of the headsets at my work gave (perhaps) the same problem when plugged in at just the wrong angle. somehow a short-circuit between the right/left channels would occur that acted as a band-stop filter for speech, unless balance was turned to one of the extremes.
