Always amazing to see folks taking these horrid AI answers instead of checking the sites that have the real information.

If your TV has RCA outputs, connect them directly to the Sonos Port's line-in.

That will work as long as you just want stereo sound and don't mind the 75 ms delay. Of course you then need a Port compatible device (Ace isn't) to make the sound as the Port has no speakers.

Add the Port to your Sonos system and create a group including the two Sonos Ace devices

Now that will be a interesting thing to see as the Ace will not Group with a Port or any other Sonos device.

If you want non-delayed sound you need an Ace compatible Sonos device that connects to the TV's ARC output. If you want multichannel sound you have the same requirement. 

So if you want to connect a single Ace to your TV you need an Ace compatible sound bar. Two Ace are not supported.

You could connect two Ace directly to the TV analog output, skipping the Port, use the included 3.5mm to USB C connector. This would also allow you to connect to the Port but it would serve no purpose and add the undesirable delay.

The Sonos Store has excellent information on the Ace and using it. No AI garbage there.
