Looking for some advice, I'm a TWC customer in Central NY and for over a year my main set up I have been using a Cisco 8640 HDCDVR set up box going HDMI for Vid and Aud ( settings on 8640- Audio -HDMI, Sound setting - Normal) into my Sony AV STR-DG820 with PASS THRU HDMI out to my TV a Samsung LN 55A 950F.
2 weeks ago I had to replace the TV with a new Sharp Elite PRO60X5FD. The only change I made was swapping out the TV's( the connections and Set ups stayed the same.) I didn't not nottice any issues until last Friday the The Audio Signalfrom the 8640 was being sent PCM instead of DD. I rebooted the 8640 and all was well again 2 days later I turn the system on and NO Audio was coming from the 8640 I rebooted and all was well, the next morning I turned the system on and back to PCM again ,Re booted and all is well. In the past (with the old TV) I did have a couple of occasions of NO Audio and re-booted 8640 and fixed the issue but nothing like this.
Is this a Cisco8640 issue or a HDMI Handshake issue with the new TV,which wouldn't make sense since I'm using the same cable box and AV Rec set up didn't change any settiings and only sending video out through HDMI with to the TV.
i can't find any threads with the Elite PRO60X5FD having this type of issue.
ANY IDEAS? Should I get a new Cisco box?
