Beam gen 2?

How do you have it connected?

What color is the Beam's LED?

Through the hdmi 3 

it was white

Hopefully the HDMI 3 is an ARC or eARC port?

Does the Controller's now-playing screen showed the Beam is getting sent audio?

There are several Samsung topics here that might have more on your TV settings, I don't know a lot about that.

Yes it’s eARC

yea and even on the tv it looks like I’m getting sound but nothing comes out 

In the Beam’s room settings in the app, try running through the option TV Setup.

Thanks
