This must be the setup for your TV box. Contact the support for your TV box.
Normaly, the TV should auto select the proper operation mode.

I have the same set, same problem with one of my MOTOROLA boxes, but not with another. I have a SONY TV that works fine with this new MOTO box, but the new VIZIO does not. The audio is coming through the HDMI cable just fine, and the fact that it works when you cycle power on your TV means it's the SYNC between the TV and the BOX. I have the identical problem and am taking back the MOTO box for another one. I spoke to VIZIO for about 45 minutes trying different things. They think it's the MOTOROLA box, COX (my cable company) thinks it's this particular box, who knows.

You can call COMCAST to have them do the reset for you or you can call the comcast automate setup on the phone, just make sure to have the serieal numbers and the MAC address. I had to do on my a couple times in about every 3 months, you can also have bad box also.
I guess you already try another box to this same cable outlet?
