I have a DCX34OO HD cable box and a Sony HBDT28 Bluray DISC/DVD Receiver home sound system and a Sony 46EX521 TV. The cable box is plugged into the sound system with an HDMI cable from the HD cable box and then an HDMI cable from HDMI 1 to the TV. The TV shows the channel picture but no sound. This has happened a couple of times before and I eventually unplugged everything and then turned them on one at a time. I also reprogrammed the remote using the codes for the sound system 1622 and the TV 0810.
When I turn the TV on (TV then Power) the TV and DVD player come on together. Then I have to remember to press CBL on the remote to get to the cable box Guide.
Is there a reason that my DVD player sound system would forget/ignore the sound from the cable box?
