How to wireless audio sync?

[hagar]

I have one HomePod connected to my Apple TV HD and want to sync audio up with video.

When TV Speakers are selected as the audio output, I can do the Wireless Audio Sync routine just fine. But as soon as I choose my HomePod (long press Home button, tapping the Airplay icon and choosing my HomePod ) the routine fails. As soon as I select Wireless Audio Sync I get an error stating “an error occurred, try again later”.

Am I doing something wrong? can I set a single HomePod as the default output? How could I get the Wireless Audio Sync up?

Depends, do you have other wireless devices on your network causing interference on your network!

I have, but no other speakers. Note that the error comes almost immediately, like it’s not even trying. This makes me think it’s a bug or compatibility issue.

You didn’t answer the over question, do you have other wireless products your network.

Lus if you use a third party router bookmark the Apple Support site
TCP and UDP used by Apple software products. So according to that site port 3689 TCP needs pass through that router for airplay to work!

As I said, I do have other wireless
products. Would be weird to only have a WiFi network for a single HomePod.
I have a Time Capsule as a router. Connected devices include some laptops, iPhones, smart home devices and tablets. No other speakers.

The ports you mentioned are open but I’ll check again if the network might be at fault. Thanks.
