Did you follow what's on p.35 of the manual and assign all your inputs correctly by connection type?
Also, are you using the A.F.D. setting on page 30?
I have a Sony Receiver model STRDE597. I have hooked up my Blu Ray and Cable box to the receiver for sound. The Blu Ray is using Coax Digital, the Cable Box is using Optical.
Everything seems fine on the cable box side. However on the Blu Ray side I continue to see a PCM 48 display once I connect to that input, I also see Pro Logic at the top of the display vs Digital. In the field where it displays your speakers, I have boxes around the rear speakers but the letters SL and SR are NOT displayed. They are displayed during use of the cable box. I must have a setting incorrect, could someone help me with the setup of a device using Coax digital so I can receiver dolby digital sound vs Pro Logic?
