tvOS 15 airplay issue

Today my Apple TV 4th gen got automatically updated to latest version of tvOS and suddenly when using airplay connected speaker (Yamaha sound bar) sound get out of sync in a very strange way. When watching any content first couple of seconds audio will be in sync then slowly audio will get more and more out of sync and some kind of video stuttering will show ( video stutter never get introduced if audio goes directly to a tv speaker only start showing when using airplay). When connecting airplay speaker to my iPhone everything works perfectly and in sync. I tried audio calibration option but always comes with error. Don’t know if someone else have the same issue, wish I could downgrade tvOS to old version.

Apple TV 4K iOS15 and Apple TV HD ios15, Bose Soundtouch 20&30 (Airplay 2 support installed), Apple Airpod |Pro;


Please yell if this should be a new issue, but it is an issue with the Audio and this is the correct audience. Specifically redirecting audio.


With IOS14 on Apple TV, login to any app, sound from TV, start streaming something, swipe down to access the Audio option, there is a list of available Airplay 2 devices as well as my airpod pros. With Apple TV + IOS15, same scenario does not list any airplay 2 devices. (Airpods force a notification onscreen saying they are nearby and can connect , I can live with that).


With Apple TV + iOS 15 the only method I can find to reroute sound to my alternate device is to access the Video and Audio settings within the Settings App->Video and Audio->Audio Output->Temporary Audio Output, select the device you want to use. Rather painful process.


I'm hoping I've missed some configuration option or that this is actually a bug. If this is an intentional redesign, its horrible from a user interface perspective. iOS14 behavior is much much better (at least for my brain)....

Ayrtonoc - how do you find the shairport-sync Airplay 2 program to work thus far? My airplay receiver is also a Raspberry Pi running shairport-sync and until now it's been bang-on perfect for a few years now. I'd rather not upgrade just for the sake of getting my apple tv to cooperate but alas, here we may be unless apple fixes support for Airplay 1 devices.


I tried downgrading the OS on my apple tv to tvOS13 but the netflix app no longer supports that OS and I can't find a signed copy of 14.7, which I'd love to revert to.

You must search the developer branch of shairport-sync for instructions on build that for airplay2 support.

It's not a fully implementation, but good for streaming audio: has limitations regarding MacOS and Windows so after inspecting this issue i've reverted to master branch of shariport-sync, that doesen't support airplay2 and, obviously, lags.


You could do a trial and told us if even in your case the workaround works

My strange volume control was happening even when I deselected the TV from the output list. The ATV did stop outputting audio to the TV but the volume control on the remote was still trying to turn the volume up and down on the TV which is sort of like a ghost effect because the actual overall perceived volume did not change but I got a visual of my TVs volume going up and down as opposed to the airplay volume and visual changing.


Interesting note about letter after alfa. Didn't know! I'll prepare for my last post to be removed :)
