My first OLED, LG OLED55C12LA, my first issue that I cannot resolve by myself. It is my first Oled Tv not my first LG TV. The C1 is connected to a Yamaha RX-V6A with a 2.1 HDMI certified cable that worked with no issues with my previous 2018 LG NANO, the one in the signature. However, the C1 refuses to transmit to the Yamaha any volume or power on-off command. The strange thing is that in input I do have two boxes with HDMI 2.
The settings are: e-arc enabled and the rest in the attached pictures. Simplink is enabled. I tried all sorts of combinations, both on the Yamaha and the C1, the only way in which I have sound is with e-Arc on.
Another interesting thing is that the remote can give commands to the Shield which is directly connected to the Yamaha but not to the Yamaha itself.
I even reinstalled the C1 twice hoping that this will magically solve the issue.
Later edit: So, to recap, the issue is that though the e-ARC is conveying sound to the Yamaha AVR, the C1 does not transmit any other command. This means that when I turn on the TV the AVR remains turned off, if both the TV and AVR are on, there is sound but I cannot modify the volume though the volume icon appears on the screen and shows that is pressed - as it is in one of the attached pictures. Also when I change the input to HDMI 2, where the Yamaha is connected, reverting to the TV means to manually change the input on the Yamaha using its own remote, not the C1, to TV in order to get sound.
Any idea what is going on here? Thank you for your help.
