What version of macOS are you using?

And the Sonos product page for Era 100 advertises Airplay 2 support.

MacOS 15.2, Apple Music 1.5.2.56. Both PC and Mac are wired, and have Bluetooth enabled.

Also noticed that your network traces are IPv4, I did a tcpdump on the Mac, and its using IPv4 and IPv6 for discovery, but uses IPv6 addressing when I AirPlay from MacOS to Era-100.

Can confirm I’m in the same boat.

Macbook: 16-inch, 2021 - MacOS Sequoia 15.2

Sonos Era 100: 16.5.1 (build 82.3 - 60160)

Macbook will not connect to the Era 100, restarted everything. No change.

If my phone is playing music to the Era, and I connect the macbook, it stops the music being played - but never connects itself.

I’ve been following along after spending hours doing the same tests and troubleshooting many described here. 

My problem is Airplay from three different Macs to a pair of Era 300s, but everything else sounds the same. I can Airplay to any other speaker in the office, except these. And I can successfully Airplay from multiple iOS devices to the Era 300 pair. 

What’s also strange is that I have the same setup at home: another stereo pair of 300s. Same network (all Unifi) and that pair can Airplay just fine from the Macbook. 

If I separate the stereo pair - same deal: Both speakers are showing the same type of error messages.

• In each case, the logs report a timeout during the initial connection phase—for example, I see repeated lines like: “Stage 1 failed, error: -6722/0xFFFFE5BE kTimeoutErr”
• That’s followed by messages indicating that the transport session is disconnecting (error -16613) and that the connection is being invalidated. 

That trick to clear the Queue didn’t work for me. 

I don’t try to Airplay all that often to these - but I think this started maybe 3 months ago (ish)? Looks like that’s about the same time as the OP. 

Fingers crossed for an update to fix this some day in the future! 

Another update: I was WRONG!

I tried last night, just to be sure. And, I can no longer Airplay to my home Era 300 pair, or either of the Era 100’s that are in separate rooms. Dang. 

That’s from Macbook that doesn’t work. iOS continues to work perfectly. And I can still Airplay from the Macbook to the Arc, Move or Ones. Seems confined to Era speakers only. 

I guess I’ll try and get this escalated with Sonos. Surely it’s something the engineering team will have to solve with an update. And if enough people do not complain, it won’t get done. 

Just to be sure, I just checked, and I CAN Airplay from MacOS 15.3.1 to Era-100.

However I CANT AirPlay from Apple Music on Windows to Era-100.

This a somewhat condensed version of what I posted in this thread regarding this issue a month ago. All results remain the same excepting that MacOS Sequoia is now v15.3.1

Range Extenders can be problematic and yes they may affect one device and not another.  Also if you have a Mesh WiFi make sure that the satellites do not have DHCP rights to create/assign IP addresses. 

• Apple Music ver. 1.5.2.56
• MacOS Sequoia 15.2
• Mac Studio_M1
• MacBook Pro 16 Inch_M2
• MacBook Pro 14 Inch_M3
• Mac Mini_M4

I removed Era 100’s as surrounds to a bedroom Sonos system which resulted in Era 100’s reverting to separate rooms (Sony 2 and Sony 3)

Using the Airplay speaker selection icon in Apple Music:

• Airplay to each individual Era 100 as a stand-alone room by checking the individual box
• Airplay to Era 100 simultaneously by checking the room box for each
• Stopped Airplay to one Era 100 by unchecking the room box and leaving the other room box checked
• Reversed #3 above

All tests successful 👍

Edit: You may need to contact Apple support for assistance as Airplay is their product….

Bottomline I’m having no issues with Airplay from my Mac’s

I have a Move 2 and experience the same issue. By chance did you change the name of your sonos speaker? My issue seems to have started when I did. It worked perfectly for about 6 months I change the name and then it would sometimes take forever to connect. Now it just does not connect. I can connect to my other Sonos speakers from the M3 MacBook Pro. And I can connect to the move 2 with my other apple devices. And even connect to the MacBooks and the move2 via airplay at the same time from my other apple devices. But the move 2 will not connect directly to the Mac. 

Hey, I just came by to check for any news about the issue. Unfortunately not :-/

I still cannot airplay from my Macbook Pro M3 to the Era 100s (2, stereo setup).

I can airplay from the Macbook to other airplay enabled devices on my network.

I can airplay from my iPhone to the Era 100s.

Interestingly, if I’m airplaying something from my iPhone, and try to airplay from my Macbook, the iPhone stops airplaying. But then the “could not connect to <<device name>>“ error message appears. 

​@markus1983 , I’m curious as to what Sonos Support said, when you called in? 

Out of curiosity, did it used to work and/or did you rename the speakers? I have the same problem with my Move 2. I can connected to it with my iPhone or iPad via AirPlay, but not the MacBook Pro M3. Used to work. I swapped names with another Sonos speaker and it stopped working. The other speakers with the swaped name works. I tried renaming the MOVE 2 something else entirely and nothing. I even went into the MacBook Pro OS’s airplay cache via command line and deleted it. Still doesn’t work via AirPlay. 

Never worked

Didnt call support.

Since it’s working for ​@GuitarSuperstar , I’m wondering why it isn’t for you. Based on that, I’m taking the assumption it may be a local issue. My own Era 100s are set up as surrounds, so I can’t do any AirPlay 2 tests of my own to them, although I only have an M1 Mac. 

I can fathom a potential difference from a windows machine, but it doesn’t make any sense to me that it is working in one user, and not in another user’s same setup case. But I certainly don’t have access to the same hard data that Sonos support does. 

​@markus1983 

You may have seen my original post (below) to this topic from 3 months ago. I’m looping back with this update.

• MacOS is now Sequoia 15.4.1
• I ran the test to a Stereo Pair of Era 100’s with Sub Mini
• I also ran the test via Mac mini_M4 alternately over Ethernet and WIFI 

All tests successful.

Below are my specifications for my Mac’s and the test procedure I used to try and reproduce your issue; which I could not. I ran the tests on each of my Mac’s. Airplay was successful in each test scenario. There’s obviously a network, software or version issue that is preventing you from using AirPlay to an individual Era 100 from your Mac. 

 I ruled out that the WIFI is turned off for the speaker as you say you can reach it via Airplay from your other device. I might ask if you have any Range Extenders on your network and/or if WIFI is disabled on your Mac?

Range Extenders can be problematic and yes they may affect one device and not another.  Also if you have a Mesh WiFi make sure that the satellites do not have DHCP rights to create/assign IP addresses.

Sonos does have the ability to do a screen share session wherein they can see your setup in real time. If you haven’t been offered such by Sonos; I would request it. 

Apple Music ver. 1.5.2.56

• Mac Studio_M1
• MacBook Pro 16 Inch_M2
• MacBook Pro 14 Inch_M3
• Mac Mini_M4

2. Airplay to Era 100 simultaneously by checking the room box for each
3. Stopped Airplay to one Era 100 by unchecking the room box and leaving the other room box checked
4. Reversed #3 above

All tests successful 👍

Good luck to get your issue resolved.

Edit: You may need to contact Apple support for assistance as Airplay is their product and you may have a corrupted MacOS. Apple Advisors can also screen share in real time. One more possibility the Network Interface Card (NIC) could be failing on your Mac

​@AjTrek1 thanks!

​@PascalDog and ​@gimball , any news?

It still does not work for me. My Macs will not connect via AirPlay to my Sonos 100s. By the way, since my original post, I added a new M4 MacBook Air. It also will not AirPlay to the Sonos 100s.

I can also confirm that I am still able to AirPlay audio from my MacBook Pro M3 to a stereo pair of Era 100s and a Sub Mini.

To those not able to AirPlay via MacOS to Era 100’s

1. Have a friend use their MacBook to see if they can AirPlay to your Era 100’s. You’ll have to setup your Sonos on their Mac temporarily and not use a Guest network.

2. Purchase another Era 100 to test with AirPlay using your Mac’s. Return it when done but be sure to make note of the serial number (take a picture of the SN on the box). Yours could be part of a defective batch that was released.

The above assumes there are no switches or access points involved on your network. Although you say you can AirPlay to other Sonos using your Mac so it may be a moot point?

If #1 proves successful then there’s a MacOS issue with your Mac. Suggest you call Apple. If not call Sonos; but suggest you try #2 first to strengthen your case.

If #2 proves successful then it’s the Era 100’s that are defective. Suggest you call Sonos.

Hi gang!

I’ll jump back in. Since my previous post, I’ve spent a couple of hours on the phone with Apple and Sonos about this issue.

To recap: I see the same problems with Airplay from MacOS on 3 different Macs, with 2 different OS versions (Sequoia and High Sierra). Also with 2 pairs of Era300s on two different networks (home and office). As well as with an Era 100. I can Airplay without issue from my Mac to any of the older speakers (One, One SL, Arc). I have no issue with Airplay from an iOS device to any Era speakers, on either the home or the work network. Problem is confined to Mac only. 

Based on all that testing, Apple ruled out any OS issue on their end. 

I had a couple of more calls with Sonos about the issue. 

Now it’s been escalated to Level 3 support at Sonos. 

I imagine that means they will eventually figure out the issue and package an update into a future release. No telling when that will be. I was told that I would not received any follow-up from the Level 3 team.

So now, I wait.

Thank you for all the efforts you’ve taken. 

Thanks ​@JHutto ! :-)

Has it worked for you? Otherwise it seems like a technical issue.

OK… ​@shanewatson 

Are you asking a question in response to another OP’s issue with AirPlay to Era 100’s or are you saying it worked for you?
