I have a year old Denon 3801 that has developed the most unusual symptom...when listening in Dolby Digital, the main characters vocals AREN'T THERE! All the good digital effects play, background voices can be heard, and there is output from all channels. Everything seems fine except that I cannot hear the dialogue. The other DSP modes work. For example, I can listen to 5 channel stereo and get the dialogue. Also, listening to a DTS encoded disk, the same thing happens: great decoding of all channels, but no dialogue. Has anyone seen this happen? Any suggestions? This was a purchase from Crazy Eddie a bit over a year ago, so I would guess I am s.o.l. for any warranty work.
