In spite of every thing that I can think to do with the sound bar system all I get is very poor muffled sound from the sound bar. I get the impression that the sound from the tv is fighting the sound from the sound bar. I have checked the setup on the 47" Toshiba flat screen and the tv sound selection does not give the ability to turn off the speakers completely. I do have the tv volume turned down to zero. Any suggestions folks. Thanks. Also when switch from a sd channel to a hd channel the volume is reduced to half of the volume on the sd channel.
