Hi, I have a Denon AVR-2309CI that recently started not playing the people talking but still plays the music when it's in Dolby Digital or any of the Dolby settings. The only way I can hear people talking is to put it in 5 Stereo. I have 2 front speakers, 2 rear speakers, a center speaker and a sub-wolfer (all Kplish speakers). Does anyone know whether I can have this easily fixed or do I need to purchase a new receiver?
switch one of the working front speakers to the center channel and see if that helps... if so then you have a center speaker problem. If not, then as suggested check your settings (speaker config) and levels along with sound processing selected. what sources are you using?
