I have a Sony ES1000 and Vizio m75 e1. Media bridge red stripe cables. HIgh speed with Ethernet printed on the cable When I connect the cable box HDMI to TV HDMI 1 ACR. Video And audio are fine. When I connect the cable box to AVR and then HDMI1 out ACR to Visio HDMI 1 no audio from TV speakers. I have changed all the settings to no avail. I know stand alone speakers are next but trying to get this going.
