Tell us how you have it setup and we will try to help. See Helson's reply above. Remember to connect the 975 to another HDMI input on the TV to ensure a complete handshake path.The key is to make sure all of the inputs to the AVR42 are all set to use the same HDMI port that the AVR42 is connected to on the 975. That way when the switching happens the handshakes can take place for both audio and video. Lets say that you have a BDP, a PS4 and a cable box connected to the AVR42 inputs and the AVR42 is connected to the 975 Using HDMI 1. All of inputs to the AVR42 have to be configured in the 975 menu to use HDMI 1 for both Video and Audio, otherwise the handshake will fail and you will be missing audio, video or both. Let us know how you are set up and we will get thru it with you. If you were complaining to Outlaw before the 30 day window passed then it should be on them to make it right, if the AVR42 is defective.
