Hello this is my first post here. I have a denon 3802 receiver and i have been having some problems with it. When i turn on pro logic II the sound gets extremely low and muffled and no center channel or anything. When i turn it up to hear sound it automaticly goes off. This happened when i was watching a movie on tv randomly one day. So that leads me to believe that it is more of a software problem. I was not pushing the reciever whatsoever at the time. However when i play through direct it sounds fine. So i think it has something to do with the processor. Any help would be appreciated thankyou.
