Well, I am currently watching The Lorax with one of my kids and have noticed some strange sounds during dialogue. I have only noticed it with this movie so far.
It sounds like bubbling, distortion, and/or popping. It is only during dialogue and not action/music scenes.
The video is over HDMI and the audio is over coax. I have an Sony ES receiver, before the days of HDMI.
My next step is to switch the coax to optical, and see what happens.
Any Ideas?? Thank You!
