LG Oled C7 and Marantz Av7703: arc issue

I have my TV setup with my av7703 pre amp.
When watching thru the streaming apps on the LG I want to listen thru the marantz but I can't get any sound out.
I have the hdmi on hdmi 1 which is the arc port and the settings are on. I can up and down the marantz volume with the TV remote but like I said, no sound comes out.
Any suggestions?

Is the arc port not HDMI 2?

Also have you turned Simplink on in the TV settings?

I tried port 2 but then I couldn't control the amp with the TV remote, I get an error msg on the amp that it can't find any arc source.
Yes Simple link is activated

I have similar problems with LG Oled C7t and Anthem MRX 1120, playing from the TV Netflix app, the audio pass through is good for pcm 2 channel, but unstable for dolby 5.1 and dolby Atmos. Link through HDMI ARC with CEC control enabled on both sides. What a disappointment as Dolby Vision is excellent, but hifi audi is zero. LG tech guys looking into the problem.
