Depends, doesn’t it? The OP could be connecting to their AppleTV with a Bluetooth connection, rather than directly with the Sonos swap to the soundbar.
Two questions for the OP…
- what type of connection are you using for your Sonos Ace?
- Have you called Sonos Support to discuss it?
When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
