this is true for me 1000% - I have 2 Sonos 5’s and they only work consistently with Roon using airplay. Every once in a while I’ll try sonosnet, but it never works. I get skips, and often teh song playing is not the one showing on Roon - Airplay is flawless.
I do have a few older sonos one’s and they work fine wit sonosnet and Roon
Who knows? I gave up…
Is anyone else still having trouble here? I have 2 x Play 3’s (stereo pair) in my Roon setup that worked flawlessly until about a week ago, but now I get “Roon lost control of audio device” error and audio cutout after about 30 secs of playing. I’ve tried resetting everything (roon server, the play 3’s, router) but still no luck.
Also tried the -nosonosflac flag

Yes, I am experiencing this. In another thread I mentioned this and thought I had cracked it. Still not solved and when grouping Sonos speakers my system becomes unstable with ‘lost control’ messages from Roon and drop-outs. I have just about tried everything I can think off. This has all been working flawlessly until about Jan of this year.
Things I have tried
My network matrix is now a mix of green and one or two yellow boxes. I still get issues though.
A few other observations.
Using the native Sonos App, grouping of speakers and playing music is absolutely rock solid.
Just using one Sonos speaker endpoint on Roon works well and no issues
Roon seems far less forgiving when speakers are grouped compared to native Sonos App.
I have two DAC units in my media room and if they are grouped ( non Sonos ). Works fine.
I may be at the end of my rope here and might consider a migration strategy to something other than Sonos.
Hi Allan I have been through some of this pain in the past. After a couple of different updates Roon and Sonos were pretty much broken for me.
I eventually got the best working solution in a long time by disconnecting all my Sonos devices from the network and plugging in my previously discarded Sonos Boost directly into a main switch and factory reset all the Sonos and adding them again one by one.
I don’t link Sonos zones that often these days as I have reduced 4 zones to use Roon Ready, but I still have 3 rooms with Sonos and two portable devices for the garden which I do link in the summer and were working nicely until I turned them off for the winter

Thanks. I actually think this is my issue. I upgraded to S2 about 6 months ago and my Sonos Bridge was no-longer compatible so was disconnected. I might go the route you did. I did just order a Boost, which is S2 compatible and supposedly better than bridge from B&H and will be here tomorrow and I will try that along with the factory reset ( didn’t want to do that, but might be my last option).
Hopefully it all goes well Allan.
The factory reset for me was to get the right devices driving network traffic, but I had owned Sonos since 2006 and tried many different things when Roon stopped working.
Hopefully the Boos will do the trick, but you might want to unplug all other Sonos devices which is what I also did, and those two things have left me with a much more reliable Sonos setup.
Good luck 
Hi Michael
So far, not so good 
My boost will be here tomorrow. For now, I just removed all speakers and factory reset. I added back two speakers, both play 3. One connected by ethernet to my router the other next door n the Family room. My understanding is, in this basic configuration the one play 3 connected via Ethernet is acting like a bridge.
These two speakers are added to my app and from with Sonos I can group them and plays rock solid. Try and do the sane with Roon and every few minutes, it stops with ‘Roon has lost control of the device’. If I just set Roon to stream to one of the Sonos speakers seems to work ok.
Lots of these kind of errors in this forum with Roon and Sonos and to be fair as many people happy with the setup. At the moment though, this does not pass the Wife test, so I need to get this fixed
It’s all very frustrating.
The Boost will be here tomorrow and will see if this is the panacea, Fingers crossed.
Thanks
Allan
Hi Allan
Yes you are correct that one play 3 on Ethernet acts like a baby boost, (but really more like a Bridge).
I replaced a Bridge with a Boost and not saying it will fix things for you, but it has for me and some others.
Ideally once you plug the Boost in, remove Ethernet from the other device’s to get the best SonosNet environment.
hopefully this work’s for you.
Can I ask if you have also reduced the bit rate on the Sonos as well? (As below). This also helped my further away devices.
I just want to share my latest experience with this issue as things have changed quite a bit at my house recently … I got a new mesh system installed! For many years now I’ve been using the SmartThings WiFi Mesh system (circa 2018) including Ethernet backhaul, but it has recently been broken by Samsung and Plume which made me search for a replacement. I got the Deco XE75 Pro x3 system, and it has resolved so many issues I had with my network that I am just ecstatic with the result.
In relation to Sonos though, it actually made it WORSE for me … I wanted to cry. I couldn’t believe it… BUT, I didn’t give up. I thought to myself “what if I go entirely WiFi for Sonos and get rid of both Boost and SonosNet?” … and that’s what I did. I researched success stories on how to properly do this to make everything all WiFi and get rid of the SonosNet network, and it’s been 24 hours now and I can’t recall the last time my Sonos system was so fast and stable. It’s amazing … huge difference for me. AND … (drumroll…) I can actually use Airplay now without interruptions! Yes … Airplay on Sonos is no longer a bad word for me. In fact, it’s actually more stable now than the Sonos network via Roon (funny enough) … so that was a flip for me.
I just wanted to share this as another datapoint. Everyone’s network, equipment and environment is different. For me, replacing my mesh system with something else (and going all WiFi with Sonos) appears to have resolved most issues. (Ahem… Roon and Sonos network still doesn’t play very well together, BUT it now works better for me over Airplay at least now in a very good way). 
That was my experience with Sonos on a Mesh network as well. A lot of modern Mesh networks do not like using 2.4 very much and if you have older Sonos then I found the Boost the better way to go.
If you have more modern devices and/or pick the right Mesh for this then it is the perfect solution. It was the one I originally tried when Roon/Sonos broke, but it was a no go with Orbi Mesh (at least for me).
Generally I think anyone with a brand new Sonos setup should follow your example, especially when employing a Mesh network.
Roon, about two weeks ago and continuing, no longer works with Sonos. What gives?
So are you recommending I swap my 4 year old Eero mesh for the Deco mesh Wi-Fi and take all my Sonos groups off sonosnet and use them with airplay?
Is it the mesh system that’s much more reliable?
I have to say that networking is a foreign language to me…I have no idea if my network settings are correct, but I’d gladly spend $200 if it would fix my Sonos issues (or improve them).
I live in a modest home, but it’s 3 stories with a lot of concrete and metal getting in the way of Wi-Fi.
All I can share is my personal experience with the change I made with the mesh network (going from Samsung SmartThings WiFi mesh to a Deco XE75 Pro x3 system), and am hesitant to say this would fix your issue (because everyone’s environment is different). I live in a heavily crowded WiFi area (multi-tenant buildings all around me and I also have plaster walls), and Sonos alone and along with Roon has always given me trouble in the 5 years I’ve had both. With that combo I could never reliably use AirPlay … but now I can with Sonos in having my new Deco mesh system.
Sonos alone (without Roon) is also extremely stable for me now since getting rid of the SonosNet network and going all WiFi with my Sonos products. In fact, I stream just on Sonos all the time now (without Roon) because its much more stable (I have a large music library which doesn’t play well with Roon which is a completely separate topic from this one). However, when I do play from Roon to Sonos via Airplay, it works much much better now and is tolerable. Playing Roon direct to Sonos speakers itself (without using Airplay) is also more reliable now, but not nearly as much as using Sonos via Airplay (remember that within Roon you can setup Sonos twice: 1) as Airplay endpoints, and 2) as Sonos endpoints … I have both setup). I don’t think we’ll ever get there where Sonos are ‘Roon Ready’ endpoints … which is a darn shame.
Having said the above, the overall best experience is to stick with ‘Roon Ready’ endpoints when you can (which leaves out Sonos). I use WiiM units as my ‘Roon Ready’ endpoints and it works great with Roon - definitely the best experience and with very few hiccups in comparison to using Sonos with Roon.
Suggestion: buy a mesh system like the Deco units from a retailer with a good return policy (e.g. Amazon normally offers Free Returns), and get the appropriate number of units (you may need more than 3 for your home(?) but can always add more later if needed). You can use the same SSID/pw so it should be pretty seamless/plug-n-play in making the switch to test it out (I was surprised how easy it was and I’m definitely no network genius). You can try it to see if it works for you with your Sonos products - if not, return it and go back to your old system until you can find another Sonos-friendly mesh recommendation to maybe try.
Hope this helps and sorry if this is extremely wordy 
Good Luck! 
Good. Never use a mesh network, they are probably the biggest scam in the consumer IT industry. They will always make your network worse and daisy-chaining your internet connection will always make it underperform with issues. I would use ethernet direct extenders or power line adapters to extend the internet, they are always reliable.
EDIT: I did not see your new comment an hour ago. I mean if Deco works for you then that is great. But I would strongly advise many to stay away from mesh networks.
I accidentally deleted the comment, my apologies. See the email that was sent to notify you of my previous comment. But essentially, buy a gaming router or more powerful router and throw out the mesh networks. They cause latency issues, underperform, and are unreliable.
A fair point - I do have my two mesh extenders connected via ethernet (and not relying on wifi) so that I get the ethernet backhaul advantage, etc. I definitely recommend connecting the mesh extenders via ethernet (if you can) if you do buy a mesh network setup. It seems like some are more friendly than others with Sonos (it would be wise to checkout the Sonos forums on other folks experience with different brands such as this one: https://en.community.sonos.com/speakers-229128/troubleshooting-sonos-on-wifi-6856334 ).
In the end, this new setup works for me splendidly for quite a few months now in having it … and I can finally enjoy Sonos without all the prior hiccups I had with my old mesh system (along with an improved Roon experience).
Thank you so much for the advice.
I have cox gigabit service with their router modem combo. I put the router in bridge mode. I have an Eero mesh system (which I’m willing to upgrade) and I’m. It sure I have the settings right. They’re all Ethernet wired but none directly to the modem (one potential issue). Then I didn’t know if they should be in automatic mode for DHCP/NAT or also in bridge mode. (They’re in bridge mode-also a big question).
Unsure about the other settings based on what I’ve read here and in the help area. Finally I was recently told (or read) that a recent Roon update no longer worked with sonos on airplay…so I’ll give that a shot.
Sonos works fine for me on Sonosnet but I’ll gladly unplug a speaker and get it all on Wifi.
Roon is also dropping out on my Roon ready Fiios Dap, so I’m positive it’s a network/connectivity thing—I’ve gotten messages that Tidal is streaming too slowly-and my internet speed is incredibly fast everywhere else in my home (I work from home and have tons of devices with no issues including streaming video on multiple tvs.
My Roon server is up to date and beefy enough i7 processor with plenty of Ram, an empty SSD drive and a usb hard drive with less than 1 TB on it.
Would you agree that it has to be router settings??
The only goofy thing I can see in Roon settings is the address for my server is preceded by several f’s.
ffff:190.x.x and no clue what that’s about.
I am grateful for the long and detailed and thoughtful response. I live in a 3 story townhouse with lots of close neighbors and my unit has an elevator so lots of concrete and metal supports that aren’t helping. But the mesh system should overcome that and I have no other device issues.
Thank you again—any additional thoughts are welcome. I absolutely love ROON and the experience. It’s like being in a library for the first time and as a professional musician being in a candy store where I can’t try enough candy fast enough. So I’m determined to getting it working…even if I have to room by room swap out Sonos for Roon ready endpoints…an expense I’d like to avoid but willing to incur.
I don’t think a single router will work for me. My modem comes into my house through a utility closet and wiring a single router to it would also be in the closet and not effective. I have 3 eero units all Ethernet wired but none directly to the modem—which I may need to do. Also may need my own modem rather than the cox isp modem which is likely a pos.
I’ve got a network guy lined up to come take a look. Everything works. And Roon worked for hours with my Sonos zones first time out of the box and then degraded. I’m also getting dropout (tracks stopping) with ONLY my Roon ready Fiios dap which also makes no sense (over wifi obviously)
Thank you for all the feedback and input. I think there’s an inherent issue with my network setup due to my noob/boomer status and total lack of understanding of basic concepts.
