Try hitting the * (star) key while you're watching the channel where the audio is out of sync. Scroll to 'Volume Mode' on the left hand side of the screen. If 'Leveling' is selected, turn it off. Exit out of the program you're watching and then resume the program and the audio should be synced.
Worked for me... Thanks
You probably need to get off CNN and tune into Fox News. Pretty sure most of your issues will be resolved.
Turning off "Leveling" worked immediately!
