Main sound system

I have a 2021 landmark Newport, and I’m trying to figure out which HDMI connection controls the surround speakers for the main TV. Has anyone used the Jenson sound system with the TV?

We have a 2018 BigHorn with the Jensen sound system. On ours the sound system is run with the optic cable to the surround sound speakers. You then go into the Jensen control and switch to optical and the surround should work
