I have an Onkyo TX-NR6050 connected to a LG OLED77C2PUA using a high speed HDMI cable.
When the TV is tuned on the Onkyo comes out of stand-by mode. The volume control on the LG remote is able to raise and lower volume control on the receiver. The LG has a connection to the Onkyo but the LG is not passing any data.
If the receiver is out of stand by mode (by either turning the receiver on first or turning the TV on --> off --> on) then there is a data connection and sound can be heard.
The issue seems to be in the timing of the handshake between the two devices. The LG has no problem turning on the onkyo but whether the data connection is established is based on the receiver being out of stand by mode first.
I tried everything found on line from changing HDMI connection type form Auto, PCM, and pass through. I have tried disabling the quick start from LG setup.
It is very annoying considering the amount of money invested into a setup that is suppose to be eARC 2.1. I should not have to use the home theater remote.
Any ideas?
