My parents have DirectTV with D11 box, it's ouput is connected to a Sony STR-DE835 receiver. EVerything worked fine untill recently when they called DTV to downgrade their service (turn off HBO). DTV I presume set out a reset command to the DTV box and it reset it back to defaults. Now they can see the picture but don't hear any sound, the Sony STR-DE835 says UNLOCK when they switch on the TV options, which mostly means that it is not receiving any audio signal on that channel...ergo DTV D11 box is not feeding the signal through audio out. I am 500 miles away so I can't set it up myself, now I went and downloaded the D11 manual which had an option for ADvanced Audio and Dolby Digital ON/OFF option, however this menu is apparently no longer part of DTV box. When I instruct them to go to that menu, they say that it's not there, the menu options have changed from the time the manual was printed. Now how do I go about restoring the D11 audio out options? Help please.
