Music won't play on multiple HomePods iOS 15.0

Reboot the wifi

Make sure the iOS device you used to set up HomePods has also been updated to iOS 15, are all on the same wifi network and signed in with the same Apple ID,

Try restarting the HomePods:

Open the Home App - Long press on the HomePod icon to bring up settings, scroll down to the gear icon, tap that, scroll to the bottom to Reset HomePod - then select Restart HomePod 

Was about to do this, but have updated to 15.1 this morning and all seems well again.

no mention of fixes for this at all in the release notes.

Prior to the update I did some experimenting. I toggled pretty much every setting on my router (there are a lot of them) to see if something was causing problems. No particular setting seemed to have an effect, but when I switched the channels for all my radios (1x2.4ghz, 2x5Ghz) and restarted it worked again for about 12 hours, then I started having the same issue. I then set some different channels and it was working well for 48 hours before the 15.1 update. Now, post update, everything is still working.

If folks still have issues I’d suggest trying different Wi-Fi channels. It seems like 15 caused the HomePods to be more sensitive to network interference somehow. Quite odd!

This worked for me! I just bought new HomePod Minis to add to my original HomePod setup. At first I was wondering if the HomePod Minis couldn’t play music at the same time as the original HomePod, but restarting the original HomePod did the trick and now everything can play together.

Have now updated to 15.1 and so far so good.

first try I have successfully been able to play to HomePod and HomePod mini together without an issue.

Starting the ticket is pretty easy.

1. Go here: https://feedbackassistant.apple.com.
2. Sign in with your Apple ID
3. Open a new case. I chose AirPlay as my category, Incorrect/Unexpected Behavior as the problem type.
4. Describe the issue with as much detail as you can. Specific products, OS versions, and the scenario that triggered the error.
5. Creating a sysdiagnose takes a little work. You can refer to this page to find your scenario and install the correct profile: https://developer.apple.com/bug-reporting/profiles-and-logs/. I used these instructions for getting sysdiagnose logs on a HomePod from an iOS device. The AirDrop part was finnicky, I had to wait a bit and tried a few times before it correctly prompted me. https://download.developer.apple.com/iOS/tvOS_Logs/HomePod_Logging_Instructions.pdf
6. Upload those files to the open issue. They are 100-300mb.

Good luck!

Confirming the same. It has been much better but issue is still there. The other day two original HomePods would just not play together in a stereo pair or otherwise. The mini and original seem better but at times only one will work. Over days. After the other update 15.1.1 they are working again but this seems only due to a restart/reset.

I am in suburbs in Australia, little interference. The access point is in adjacent room. And pods on a desk together.

again some months ago no issue was flawless. Frustrating.

On 15.1.1 and I've also experienced the popping noise and speakers suddenly cutting out. After rebooting the speaker it typically works again (unlike before, where nothing seemed to get a speaker to reconnect).

FWIW, when debugging I found that AirPlay to a Samsung TV was also exhibiting similar symptoms, and it streams 4K video without issue and lives next to the WiFi 6 router.

Unfortunately I don't, but I'll point out that the same thing happen using macOS as the source.

Oh, another interesting detail, same problem when I made my Samsung TV a "multiple". No sound from it, while the first HomePod played fine. When I ended the AirPlay session and started with the Samsung TV it worked.

So perhaps the issue is in AirPlay 2?

Just bought a new Eero Pro setup and have the same issues. Restarting a HomePod temporarily resolves the issue, then within a day it typically starts failing again. This is really frustrating, at this point I seem to have almost two thousand dollars of useless speakers.

Ditto, same issue and I tried using different wireless modems, networks, etc.

It definitely seems to be a bug within the home app and/or the homepod software itself.

Wanted to let folks know that the issues have reappeared for me. I think the combination of WiFi channel changes and the reboots with 15.1 may have made things better for a bit, but a few days ago speakers stopped connecting again.

To frame this — speakers with very high SNRs of 39db and connection rates of ~850Mbps are having issues. No speaker is more than 25 feet from an access point, and speakers with a clear line of sight are having issues. I never had issues before maybe 3 or 4 months ago, now it's frequent. I am in Brooklyn, NY, so there's bound to be network interference, but this level of sensitivity seems odd.
