@kezo Yamaha RX-V373 about 10 years old. Panasonic TV also about 10 years old Blu-ray player connected direct to TV HDMI 4 AV Receiver connected to HDMI 3 (eARC) Using AV Receiver remote works fine but doesn’t display the volume level on the screen.
Cheers I’ll have a proper look later today mate 🙂
The proplem with CEC is there was no real set standard among manufacturers meaning setup can be slightly different among manufacturers, even turning one device on before the other can cause handshake issues and so on – Samsung for example is one of the worse as they don’t have HDMI certified ports. The introduction Enhanced ARC technically removed the need for CEC as HDMI cables incorporated ethernet so the handshake was done for you although not always seamless. AV manufacturers such as Sony, Pioneer and Technics (I have) offered firmware updates ARC-EARC.
Some things to try in the mean time.
Remove the HDMI cable >Turn off HDMI CEC settings > Turn off both the TV and amp and unplug them from the wall for 10 minutes, hopefully this will clear the cache without the need for a reset.
Turn the TV back on > Grab the original remote for now.
Navigate to settings > Speakers > TV speaker > Turn off TV speakers or choose audio out and select HDMI ARCÂ if these are available.
Navigate to System > Scroll down to HDMI CEC > Turn HDMI control on > Take photos of this page for me.
Connect the HDMI cable – if possible use a certified HDMI 2 cable.
Turn on your Amp
The TV and amp should now be connected (I say this lightly)
Further things to try:
Ensure ARC is still turned on on your amp
Turn HDMI control off and back on, on your Amp
Set the AV audio channel on your Amp to match that of the HDMI port on the TV and turn HDMI control off and back on again.
Try this first then if necessary we will move on further and please take into account the setting above are a guide and may vary slightly, on name and how to access them 🙂
Have you got your set up as 5.1 sound or just two speaker stereo with sub?
