Airplay 2 sync issues

SomeGuy917,

The following article has some helpful steps which may help:

If you can't use AirPlay or mirror your device's screen - Apple Support

"If your content gets interrupted or your network lags

If you have a weak Wi-Fi signal or interference from a nearby device, like a microwave or baby monitor, try the following:

• Make sure that you use the recommended settings for your Wi-Fi router.
• Move or turn off other devices that might cause interference.
• If you're trying to AirPlay to Apple TV, try connecting your Apple TV directly to your router with an Ethernet cable instead of using Wi-Fi.

Your AirPlay connection might get interrupted when you lock your device, put it to sleep, or switch to a different app. 

If you still can’t use AirPlay after trying these steps, contact Apple Support."

Take Care.

I understand from your post that you have a delay when using AirPlay 2 and your iPhone 8 with 3rd party speakers. Make sure that you have devices that meet the system requirements for using AirPlay 2 as described in the article below:
