Digital cable box sound
I have a cox digital cable box with built in DVR. I have the sound routed from the cable box to a Yamaha HTR-5790 receiver via an optical digital cable.
Sound plays through the receiver for movie channels (HBO, Cinemax, etc.) and when playing a recorded program from the DVR. However, for all other channels, sound will only play through the receiver if I slightly back-up (i.e., watch live tv slightly delayed) the program.
Any ideas what the problem is?
