AVR 4306 Dolby Digital Problems
I've just upgraded my AVR 3802 to the all singing and dancing AVR 4306, however I have something strange going on with the sound.
I am using optical inputs for all my components, Sky+, Xbox and DVD.
When playing a DVD with Dolby Digital sound in either my DVD player or in the xbox, I only get some of the sound appearing. I get the soundtrack and some effects, but the speech doesn't come through. Sometimes I can hear the speech in the faint background, but it's muffled.
However when I switch to stereo, 5CH stereo or such like, the speech comes through fine. It appears the dolby digital decoder in standard mode isn't working properly, or I've configured something incorrectly. DTS DVDs are also suffering from the same problem.
I even tried running the latest pro evolution soccer XBOX game (Dolby Digital Audio), and all the footy game effects were present, but the commentators speech was missing, despite it being turned on. Again if I switch out of the Dolby Digital standard mode I hear the speech with everything else.
I've got the usual 5:1 setup, using two rear speakers as surround A.
Has anybody got a clue what's going on?
