I have an AVR-1713. When I play Blu-rays and DVDs, I cannot get hear speech. I hear music (including singing), sound effects, etc., just not speech/dialogue. When trailers are playing, occassionally the display (on the unti) will change from "MULTI IN" to "STEREO" and I can hear dialogue. With my set-up, I only have 2 front speakers (which is how I configured the unit settings).
I have tried both a soft reset and a microprocessor reset. I have also checked all the connections.
Any advice would be appreciated.
