tvos 14.5 wireless audio sync issue

This is correct, but that’s not the issue here. The issue is that it’s not possible to put the Apple TV into 24Hz picture modes to perform wireless audio sync for those. That means that when using Match Content settings, your audio may be out of sync. I’m assuming this is either a bug or an oversight, as Apple’s own support documentation that explains how to do Wireless Audio Sync with Match Content on (https://support.apple.com/en-ca/HT210526) says to switch to other modes. Those modes just aren’t available in 14.5.

Urquhart1244,

According to Apple, Wireless Audio Sync calibration should be performed for each supported refresh rate. When Match Frame Rate is enabled, the Apple TV will switch to 24 Hz or 23.97, neither of which can be selected in settings. Therefore Wireless Audio Sync calibration cannot be performed on the most common refresh rates for movies and series. Users are forced to disable Match Frame Rate and suffer through 3:2 pulldown, or deal with audio that is out of sync.

It's not only the sync issue. When Apple tv "Match the frame rate " is not the same as setting it naturally at 24hz . Before that movements were natural, just like in movie theatres. Now the "Matching" process create some artefacts and it not as before. It lost the "Movie effect" I am so disappointed, because I mostly watch movies. -_- . I really don't understand why they needed to remove the setting -_-

Exactly the same situation for me ! I was using a sonos one plus a bose solo 15 on ios 14.4 et all was fine , audio was synchronise perfectly, and now it's a mess ! I can't using my sonos one with airplay in combinaison or not with my bose , wireless audio isn't synchronised anymore !

PS : Sry for my english i'm a french user !

Just upgraded and audio sync is busted with airplay with two HomePods in a stereo configuration set as the audio output defaults.

When performing the “Wireless Audio Sync” the control lights on the top of the HomePods go off as if disconnected from source, which is likely, and the calibration audio comes through the TV speakers. Following, the TV speakers remain the default audio option for a moment, but then, as if AirPlay has reawakened on my Apple TV, the connection to the stereo HomePods is re-established.

This all worked before on14.4 with not a single issue, so this is not some weird frame rate / refresh rate / audio calibration issue as noted in prior posts. This is a broken tvOS 14.5 production release that’s just introduced a regression that should have been found by QA before release. So very disappointing to see such an impacting bug unleashed on a platform that’s literal job is to seamlessly play sync’d audio and video.

mahoneybellevue,

Wireless audio sync measures audio from the TV speakers to calculate the delay introduced by the TV.

You post seems like you are complaining about the TV speakers being used during wireless audio sync, but that is exactly how it is supposed to work.

Thanks for the report. I had turned off Match Frame Rate waiting for this to get sorted out.

Did you have to run wireless sync again, or did it remember the previous calibration and apply it correctly now?

I only updated my AppleTV4K and when 14.6 was installed I selected my sonos one in airplay menu it was perfectly synced with my previous calibration that was made in 14.5 with no success .. ( this calibration was made after a factory reset in 14.5 )

Wireless Audio Sync in now available from:

Settings﹥Video and Audio﹥[ᴄᴀʟɪʙʀᴀᴛɪᴏɴ] Wireless Audio Sync﹥

I really hope there is a resolution to this soon. I am using my Sonos One for the audio when watching with ATV and on TVos 14.4 it worked when using the the wireless audio sync calibration at 24hz.

For your information for me it's not working in 60hertz / 59 hertz / 30 hertz

Same problem, Apple TV not sync audio with Bose tv bar sound tvOS have software error for this feature. 😟

TV OS 14.6 fixed the problem for me ! My sonos ONE is now perfectly sync with my boso solo 15 ! Just like before !
