After iOS 16.4 update to iPhone AirPlay says cannot connect to hhhh HomePod,

Hello ozarkcanoer,

Thanks for reaching out to Apple Support Communities regarding one of your iPhone's not connecting to a HomePod.

Let's try the steps below to see if we can get it connected and working again as expected.

"Restart HomePod or HomePod mini

1. Open the Home app on your iPhone, iPad, or Mac that's signed in with the Apple ID that you used to set up HomePod.
2. Tap or click HomePod.
3. Scroll down, or tap or click the Settings icon  and scroll down.
4. If you have two HomePod speakers set up as a stereo pair, select Restart HomePod. If your HomePod speaker is not set up as a stereo pair, select Reset HomePod, then select Restart HomePod. 

If you don't see an option to restart your HomePod, unplug it from power, then plug it back in and try again.

If HomePod still doesn't respond, reset it.
