Audio sync problem with multiple HomePod after update to IOS18

Why do all my Homepods play the same music at different times after updating to IOS18? It doesn't happen in IOS17! There are more than 5 Homepods in my place. After I started to play for a while, maybe 3-5 songs, the audio does not sync anymore! It does like the delay time is a mess with the system!

HomePod, 18

Same here after iOS18 and HomePod OS18. Located in Austria/Europe! And sometimes a crack in one of the speakers. Four HomePods 1st gen in use.

Brilliant! This was the clue that seems to have my heterogeneous HomePod system back in sync!


The fix for me, at least, was to go into the Settings for my gen1 HomePod and disable all its listening features - Siri, alarms, everything. I already have a pair of HomePods in the room, after all.


And I’m now three songs along in testing, gen 1 and gen 2 pods are in perfect synch, and I believe you are my favorite person today EmmetPratt 😄


… oops. Nope, spoke too soon. Just started doing it again ☹️


Well, back to the debugging board.

Same for me. TERRIBLE bug that seems to throw off the sync between homepods completely. I had to turn off lossless and dolby atmos that used to work perfectly fine on 17. Speakers are also crackling and then stops playing. Hope it doesn’t damage any hardware. Can’t believe Apple passed this update. I’m better off using a JBL bluetooth speaker. No update yet one month in :(
