Stereo Pair Randomly Unpairs After 13.4.8 Update

Some things you can try:

• Unplug the homepods for a few seconds 
• lift the homepods off the surface and rock them gently to recalibrate. When they think they got moved, they adjust
• try asking them to play music to all, both or everywhere - this may get them back in sync
• Use another app: Go to a different app on your device which uses HomePod and see if it pairs. This may restore sync.
• Try swapping left and right - back and forth a few times.
• On the iOS device that you use to set up HomePod, make sure that you signed in to iCloud with your Apple ID and turned on iCloud Keychain. You also need to have two-factor authentication set up for your Apple ID.
• Make sure that your iOS device has Bluetooth turned on and is connected to your home Wi-Fi network.*
• Reboot your wifi router - unplug the router for 30 seconds

If they still don’t work:

•  you can also sign out of iCloud in the home app,  then sign back in 

• repeat the ungrouping process 
• manually remove both from the Home app and set up again  (you must Ungroup first) 
• Reset HomePod - Apple Support

sounds more like it’s the music app from your iOS device.

Please perform all below steps:

If the Music App isn’t responding 

Make sure your iOS software is up to date

• Close the music app- How to force an app to close on your iPhone, iPad, or iPod touch: https://support.apple.com/en-ca/HT201330
• in Settings- General - Reset - Reset Network Settings
• Restart your iOS device  (until the Apple logo appears)

Thanks for your reply. I tried your suggestion but it did not solve the problem.

(but perhaps it was part of the solution)

After resetting Network Settings I followed your first advice again (which I had done before, but prior to resetting Network Settings)

• Unpaired the HomePods.
• Unplug the homepods for a few seconds 
• lift the homepods off the surface and rock them gently to recalibrate.
• Reset the HomePods and then re-paired them.

It's only been a few hours but they seem to work as a pair now.

None of the above works.

So frustrating! such a beautiful sounds, such a horrible interface.

I have 4 stereo pairs, the two pairs that I’ve tried the above fix on no longer show up as a Stereo pairs in control center nor the music app, but home app shows them as pairs. All 4 sets either randomly drop one of the pairs, slowly start playing out of sync or L and R play different music.

Or if none of the above works

You can let Apple know:

One week working as they should! Thank you!
