I have started experiencing an audio issue while watching LOST: Season 6 on blu-ray. 4-5 times per episode, the audio gets messed up and when I pause and play again it corrects itself until it happens the next time. I don't know the technical term for what the audio is doing, but it's like the center channel audio gets sent to all 3 fronts, and so dialogue sounds like it is echoing -- like it's coming from the bottom of a well.
I have an Oppo BDP-93 connected via HDMI to a Denon AVR-2809, and the HD audio track is selected. I didn't experience the issue on any of the 5 previous seasons of LOST, but I can't find any discussion of audio problems with the 6th season, so I'm wondering if something has started happening with the Oppo or Denon, or the cable. As mentioned above Pause/Play temporarily corrects the issue.
I appreciate any suggestions!
