I just connected my Sony tv to a Samsung HW-Q90N sound bar via the ACR port on both units. I also connected the sound bar to an Apple tv and a Cox cable box. All connections use HDMI cables. The p...

Bruce, I am not blaming anyone. I am trying to find a solution for the problem I am have with my sound bar. You said cheap cable boxes do not support HDMI-CEC, so now I need to find out if Cox has an HMDI enabled box.
As far as I know, all Cox cable-boxes are HDMI enabled. If your cable box has HDMI ports, it's HDMI enabled. HDMI is hardware. HDMI-CEC is a protocol.
I don't even know if CEC is your problem. I just suggested removing the cable box from your CEC bus...if applicable...and we'd go from there.
HDMI is designed...fundamentally...for copy-right protection (HDCP). With HDMI, you'll only get audio/video if connected to a display device or an authorized recording device.
It sounds like if everything is powered, the soundbar bridges an HDCP connection from the cable box to the TV. An authorized connection. However, when you power everything down, the cable box loses that authorized connection (bridge) and revokes the license (HDCP) because it only "sees" a soundbar.
I understand that CEC is the protocol that runs over HMDI and when working properly it enables the user to use one device to control all of devices connected using HMDI cables. In my situation, I am using Sony's Bravia Sync to control the connected devices. With Bravia Sync activated, I am able to see that the sound bar and the Apple TV are connected, but not the cable box. Additionally, I am able to control all of the devices except the cable box with the Sony tv remote using the CEC protocol. That is what I meant when I asked if the cable box supports the HMDI-CEC protocol.
