Thanks for the assistance folks. I first tried the simplest HDMI fom PS$ to input on AVR and HDMI from AVR out to Sony TV. No video at the TV and no audio from the AVR.
I may not have the settings correct. I can get to the settings on the tV, but how do you get to the settings on the AVR?
Since I could get the TV to display the video directly from the PS4, I thought I could simply add the audio/digital cable from the PS4 to the AVR in order to get the sound. Again, this could be a settings issue in the AVR but I don't know how to access these settings.
Again, thanks.
