tvOS 14.5 - Homepod Audio sync issues

Not sure if you reset the Apple TV or HomePods or both?

The HomePods may have updated also, if you had them enabled to automatically update. If not, then update the HomePods to 14.5 as well. If it’s still not working restart or reset HomePods Reset HomePod - Apple Support

• Update the software on the iOS device you set up HomePods with
• Try restarting them first.

A Reset or removal will require setting them up again

You can choose to do a hard Reset by pressing the top or via the home app- long press on HomePod icon, scroll to gear icon, scroll, to bottom - Remove.

To Restart them, from the Home App in HomePod settings - choose Reset - then Restart

I had exactly the same issue. Restarting and resetting the homepod and after calibrating the audio numerous times, it didn't fix the issue unfortunately. The workaround I did which worked is as follows:

1. Turn off both Dynamic Range and Frame Rate under Settings->Video & Audio->Match Content
2. Do the calibration again under Wireless Audio Sync
3. Turn on both Dynamic range and frame rate under Match Content

I noticed there's still a very slight delay between TV speaker and homepod when I play youtube videos and music but when I play Netflix and Apple TV contents, they are well perfectly synced. Hope this helps.

Ok I think I have a solution for you people - at least these steps seem to work for me:

Setup - two Homepods and one Apple TV connected to LGTV with optical connection to two KRK monitors. All in different rooms (configured with Home app on iPhone iOS14.5)

After upgrading all devices to 14.5 - Homepods were out of sync with ATV/KRK - I hav previously factory reset all devices and couldn't get SYNC working as it was before 14.5 upgrade!!!!!

So, this is my recollection of the steps to getSYNC working - good luck, I hope this works for you

I moved the Homepods next to the ATV, and used Home app to configure Homepods into the same room (living room) and also configured as "paired".

Then I set the ATV to use the Homepods as audio out (ATV Settings - Video & Audio - Default Audio Output - Select - Homepods

Played some ATV through them and while a show was playing, next step,

From iPhone I played music and directed the music to the Airplay - in my case the "Living Room" (which was Homepods-Pair) and then added the ATV speakers to the airplay list and F-me it played in sync.

Then I un-paired the Homepods - still all in sync

Then moved the Homepods back to different rooms and I can airplay to all three devices IN SYNC - F-yeh

It sounds awesome again with ODESZA filling the place with music IN SYNC

update 14.6 solved my sync issue with ATV and my Bose smartspeakers. Everything runs smoothly again.

just did the update and ran a new sync.

Problem fixed with the update to 14.6.

I'll never get the 2 hours back of trying to problem solve and resetting of all devices.

Figured a solution. Turn on av sync AND bypass on tv settings (I have LG 65inch 4K). My set-up is optical out from tv to external front 3.1 Bose speakers. I use HomePods for 3D surround effect. Also with Apple TV 4K do NOT use audio sync calibration just reset this. Bingo everything as it was and beautiful sound in every app I’ve tried (Netflix, youtubetv, etc). I hope this helps with 14.5 update.

I have the same problem when trying to sync my Sonos speakers. The problem is that apple took out the option to calibrate all formats for 24hz. It was on there for TVos 14.4 and have no idea why they took it out. Most movies/shows are 24hz format and will always be out of sync until we can calibrate under that again. Please fix this apple!

Problem exists in 14.6 as well. It's not just Homepods. It's ANY sound system. Can't watch movies from my Mac mini library through my HiFi stereo system either. Sound starts out fine then gradually gets out of sync. Go back 10 seconds and it's fine at start then gradually gets out of sync again. It's impossible to use. There is NO tweaking fix for this. My solution (not for everyone), was to replace my Apple TVs with new, old ones that still have 14.4 on them, turn off auto OS updates. When Apple Stores open up again, I will "donate" the old ones to them.

I have the same issue although I'm using bose smart speakers within my audio environment. Just recognized when switching off/reset audio sync within the apple tv 4k setting (don't run a new setup!) sync is much better when using airplay but still not 100% perfect.

can you try to reset audio sync on aTV. Don't run a new setup. just try it without audiosync. How big is the sync issue now! In my case it got better bit is still not 100% perfect.

Reboot the wifi router as well. If this is one app doing it that might be the culprit. Although if you reset the Apple TV you would have installed the latest versions of other apps.

Any time this happened with mine, I would force quit the app & Restart Apple TV. Or even restart the show from the beginning. There are some shows that appear to be doing this when they’re not, if they are dubbed versions. Their mouths aren’t moving in sync with the sound.

Yes, brutal sync issues with 14.5. When playing some mp4 videos on my ATV that sit on my MacBook Air (Silicon) the audio slowly gets ahead of the video and continues to drift further ahead (I'm on a 1GB line). In five minutes it gets about 5 seconds off. If I pause and immediately play it is resynced. And starts drifting again. It NEVER did this in any earlier OS. If I convert the file to a massive mov it will properly play. I reset everything from scratch. Even more frustrating is that it is only some of my mp4s, not all, although they all have identical compression and format (as far as I know). The "bad" ones are consistently bad, good ones always good. Really hope 14.5.1 fixes this. Starting to regret buying a pair of HomePods when they first came out to go with my ATV. :(

PS. There are zero problems when using apps such as Netflix, Amazon, ATV+ directly on my ATV.

Hi. here in France with atv 4K 2 homepods and 2 mini (in other room). I have the same issue here but the french customer service seems to discover it.

dont know what to do :

A downgrade in a apple store ?

get the new atv? In that case Apple should take back my old one !

Tried this approach, turning off match content - sync again - turn sync back on. Audio still out of sync from ATV to home pods
