The new update is causing this sync issue between hardware that implements airplay2 and airplay1.
See this thread below.
Thanks @Paul_Kabuubi will keep my eye on this thread hope fully a fix at the end of this sink issue I had for a while now…
Hi @daniel I will have to go back on the new version playing flawlessly with AirPlay2 devices
I’m afraid I have just had 1st out of sink playing to my 3 AirPlay2 Devices 2 Home Pods + Naim have the Zeppelin muted (as this will not sink at all) and it happened more and more today 
Hi @GillysHere,
Like @Paul_Kabuubi said we have some other reports of AirPlay sync issues. We are currently investigating. Once I know more I will let you know.

A ticket for this has been given to the dev team. I cannot comment on a specific timeline. It’s good to know that Tuneblade is working.
I’m posting as I have a similar problem. My case is with a Homepod Mini and Ropieee Airplay. Ropieee is consistently a little late. However, when I play to the two speakers using Apple Music, the sync is fine. This suggests a Roon issue, but I’ve tried various settings and nothing seems to change. Happy to try anything different…
As @daniel say
Blockquote Hi @GillysHere,

Sorry it’s no help but we are all in the same position hopefully, they’ll have a fix soon……
Hi @GillysHere and @Kate_Sorrels,
You are correct in that our team is still in the process of investigating this issue, we apologize for how long-standing the issue has become!
My apologies if this has been glazed over, but have you attempted to first add all your airplay 1 devices to the apple home app prior to using them with Roon? Here’s more info and steps to do so:
Let me know if you’ve already tried this and if it makes any difference! 
Hi @benjamin
Yes I have. I have mentioned before maybe in a different post i’ve been doing a lot trying to get it to work in sink so I could be in a multiples of this same topic sorry. I can’t find the original one, but my 1st gen Zeppelin Air is too old so it will not add to Apple home and I have a big missing speaker in my open plan area 
Hi @GillysHere,
This is something I’d get in touch with the manufacturer directly to inquire further. Your chances of success with devices a bit more up-to-date will likely increase if thats something you’d consider in the meantime as well.
Hi @benjamin
Thank you for your previous response. As suggested, I will be reaching out to Bowers & Wilkins directly regarding my AirPlay 1 device (Zeppelin Air). However, I wanted to provide more details about the issue I am experiencing, as it might be helpful for both parties.
The main problem I’m encountering is that my Zeppelin Air is not syncing correctly with my AirPlay 2 devices when using Roon. Despite the fact that AirPlay 1 devices are supposed to remain compatible with Roon (as mentioned in your AirPlay 2 update), there seems to be a noticeable delay or out-of-sync playback when grouped with AirPlay 2 devices, which is affecting the overall listening experience.
Your blog mentioned that “first-generation AirPlay devices will continue to work seamlessly with Roon,” but this syncing issue is causing some frustration. I wonder if there are any settings in Roon I should adjust or whether any future updates might address this particular compatibility issue.
For your reference, here is the blog post that discusses AirPlay 1 compatibility:
AirPlay 2 arrives in Roon.
I would appreciate any advice or insight you could provide regarding this issue.
Hi @GillysHere ,
Thanks for the additional details. We are still looking into this on our end, but do let us know if you receive any reply from B&W. The main tracking thread is below, I would also monitor this thread for any updates:
Hi @noris & The Roon team,
Thank you for your response and for sharing the main tracking thread. I wanted to let you know that I’ve now logged a ticket with Bowers & Wilkins regarding the syncing issue with my first-generation Zeppelin Air (Firmware version 2.04.05 (9112)) when grouped with AirPlay 2 devices in Roon. I’m currently awaiting their feedback and will keep you informed of any updates.
I also wanted to take a moment to acknowledge the hard work you’re putting into evolving Roon and adding great new features. However, I believe it’s crucial that these enhancements don’t interfere with the core reasons people use Roon: its stability, reliability, and, most importantly, the quality of the sound. These are the foundations that have made Roon such a trusted platform for audio enthusiasts like myself.
Thanks again for your support, and I will continue to monitor the tracking thread you provided for further updates.
Thanks @GillysHere! We’ll keep this thread open incase you hear back from B&W.
Here is Bowers & Wilkins response.
Hello Paul,
You recently raised a question with our customer care team. Below is a summary and our response.
Reference Number: 240913-000018
Subject: AirPlay 1 Device Syncing Issue with AirPlay 2 Devices (Zeppelin Air First Generation, Firmware Version 2.04.05 (9112))
Response By E-mail (Neil) (13/09/2024 14:58)
Hi Paul,
Many thanks for getting in touch.
Unfortunately, Other than for basic setup advice, these speakers are outside of support, for updates or servicing.
The Zeppelin Air speakers were designed using a network board manufactured during 2009, which included Apple’s Airplay 1 hardware of the time.
We can no longer obtain support for this chipset or the complete board series within these speakers, as the sub suppliers who manufactured these have also ceased operation.
Sorry we are unable to help on this occasion.
Best regards,
Neil

Dear Bowers & Wilkins Support Team,
I hope you are doing well. I am writing to report an issue I’m experiencing with my first-generation Zeppelin Air (Firmware version 2.04.05 (9112)) when grouped with AirPlay 2 devices in Roon.
Since Roon’s recent AirPlay 2 update, I’ve encountered a noticeable syncing problem: there is about a one-second delay between the music playing on my Zeppelin Air and my newer AirPlay 2 devices when grouped together. This issue only started after the update, and it wasn’t a problem before.
It’s worth mentioning that all of my equipment is connected via Cat6 Ethernet cables, and I am not using Wi-Fi for any of my speakers (including theZeppelin Air). I have read that some other manufacturers (such as JBL and Cabasse) have resolved similar AirPlay issues by adding their devices to Apple’s iOS “Home” app, which has improved syncing with Roon.
Could you please advise if there are any similar updates or recommendations for my Zeppelin Air, or if there is anything else I can try to improve its performance when synced with AirPlay 2 devices?
Thank you for your time, and I look forward to your guidance.
Best regards, Paul Gilson
Got it, thanks for the response @GillysHere. Our team still has a ticket in for investigation, but I should mention that progress will likely be slower than usual, unfortunately.
That said, I’d be curious to see - do you have the option to change the ‘Clock Master’ priority when you have your airplay devices grouped? You should be able to find this within the zone settings.
Let me know if you have this option, and if changing it to a different device (maybe even the Zepplin just for testing purposes) has any difference in playback.
Hi @benjamin thanks for your suggestion, I do not see a Clock Master option in Zone Settings I think I’m in the correct place here is some Pictures…
Thanks for the suggestion. Yes, I first added the airplay (which is actually Airplay 2) devices to the home app. Only afterwards did I try to sync via Roon. So it appears not to have made a difference. I too can’t find any any “Clock Master” settings in the Zone options.
