Hue Sync box, Blu ray player, HomePod Theatre sound

Just got my Hue Sync Box, love it! The video is working perfectly with my AppleTV and 4K blu ray player. To get eARC to work for AppleTV, I had to put the corresponding HDMI from the sync box to the port on the TV that has eARC (port 4). Worked great!! But now, when I’m using the blu ray player, I get no audio. Any idea??

Are you using the Hue Essentials app?

I am not using that app

What do you do here if you don’t use the app .

I figured since this site is all about Philips Hue lighting, someone would have some kind of insight. I’ve tried other sites and Philips themselves, but have come up empty everywhere.
