New Panasonic TV issues

I recently bought a panasonic TC-P60U50/U54.

I have a harmony one remote, which switches on the TV, reciever and sets the right Hdmi ports on the Tv and the yamaha reciever. The problem is the sound doesnt come thru the reciever and the speakers. When i increase or decrease the volume i dont get any sound thru the reciever speakers.

If i switch off the reciever and switch it on with the yamaha remote then everything works fine.

Please advice.

Thank you

Problem solved. Just switch off/disable viera link . I didn't need it anyways. Problem was the remote code was interfering with the Pannys CEC- HDMI control, if that makes any sense.

Thanks,
