Have you tried moving the output cables from the "Fixed" RCA plugs to the "Variable" RCA plugs or vice versa? Have you tried using the TV coax output on channels 3 or 4? Have you tried lowering the volume output level on the 922 itself? Have you tried changing the TV settings from "Normal" to "Wide" or vice versa in the Viewing Settings sub-menu? Have you tried a rehit? Just guessing. If it's a new installation, I hope it's still under warranty. Good luck.
