I need some help, Vizio's techs are pretty much clueless. I have a new 55, I have one HDMI cable running from the TV to a Denon AVR 400 into the ARC HDMI port on the receiver. I am running a CISCO cable box, and Apple TV. Sound is fine through the receiver on everything except VIA. My issue is that if I switch to VIA and attempt to use any of the apps, I have no sound through the receiver, or the sound from the cable box, even if it is off. If I turn the TV speakers on, I do have sound from the apps. I have tried using a different HDMI port on the TV with no sound. It appears that the TV uses a different input for the apps.
Vizio basically told me that the problem was the receiver and they couldn't help me?? Any ideas????
