Description of Issue

Regular glitching after a few tens of seconds into a track.

Hi @Gareth_Jones3, welcome to the community. A fellow user here, but are you Sonos speakers connecting together via SonosNet or are they attached directly to your WiFi or cabled Ethernet network? Roon seems to have less connection issues when Sonos devices are connected directly to the network rather than using SonosNet.

Thanks for the welcome.

They’re running SonosNet. (WM:0) , although I’m sitting listening to a Connect right now which is one of the wired endpoints and it is glitchy as anything - unlistenable. Needless to say all of this is rock solid through the Sonos app. This connect is too old to support AirPlay so I can’t switch protocols.

I guess I could unplug all the ones that are wired so everything flips to WM:1 wireless mode, but for general Sonos use/syncronization, that’s not recommended.

You only want to wire one device, and they all should indicate they’re on WM: 0.

Yeah, I had two wired, and they were all reporting WM:0

I’ve unplugged one of the two, so now only my Arc is wired and still the connect is glitching all over the place.

Was one of the wired devices a Play:1 bonded to the Arc as a surround sound speaker? If so, that won’t work to have it wired even if the Arc isn’t. It won’t trigger the formation of SonosNet, and will only create problems otherwise. Actually only having your Arc hardwired to your router is the way to go in my opinion, just like I use my Playbar.

What is your exact setup? You mentioned initially a Connect and paired Play:1s, but not your Arc.

Edit: and by the way, you’re going to need to power cycle everything eventually in order to see if things are working properly … i.e., your router and any other networking gear, along with all your Sonos devices and whatever you’ve got connected to the Connect, as well as restart Roon, etc.

Here’s my all up on Sonos. As of 30 minutes ago, only the ARC has a wire.
I’ll go and yank that out in a minute and see if it is any better on WM:1 Wifi.

There’s also a wired BluSound node.

Ok, thanks for that screenshot. So my advice about lowering the bit depth to 16 isn’t really applicable here. The Play:1s are bonded to your Arc, which definitely supports 48/24, so I’d leave Roon’s default settings for your Living Room alone for now. Except for the Connect, all your other Sonos devices are new-ish, and support 48/24 as well, so they’re fine. You might want to lower the max bit depth to 16 for your Office however.

So I’d do that, power cycle everything, and give it time to all come back up so all devices appear in the Sonos app and all your rooms appear in Roon, and see if things are working better.

Would you also share a screenshot of what Settings>Audio looks like for you.

If you have older Sonos s1 and s2 try changing the max rate to 16bit for all of them and see if it helps.

@CrystalGipsy, all his devices are on S2. I suggested lowering the max bit depth to 16 initially because he only mentioned a Connect and Play:1s in his OP. Turns out he’s got an Arc, Ones, One SLs, and a Roam.

Edit: and if he initially had one of his surround sound Play:1s hardwired, in addition to his Arc, then this is most likely the cause of his troubles in the first place.

I can confirm I never had any of the Play 1s hardwired

ok, thanks for that. Which speaker did you have hardwired?

Originally I had the Arc and the Connect hardwired.
Then just the Arc
Now none.

No apparent difference although I’m still working through rebooting everything, cos reaching some of the power cables is a bear.

Also I don’t play any music through the Arc and it’s not enabled in settings/Audio - it’s just my TV’s surround sound system.

The clipped ones at the top are just the local PC audio devices which are all disabled.
The AirPlay option for the master bedroom seems to have vanished.

Everything I’m suggesting is based on having one device wired so SonosNet is created and used by your devices. Did you try power cycling everything first before unplugging your Arc to make sure that that configuration is still not working for you? If not, then I’m afraid we still don’t know if that was a possible solution.

Edit: ideally what you want is for all your Sonos devices (except for the Roam) to appear under Roon Tested if you’re using SonosNet.

I’ve never seen them all under Roon Tested, so that’s interesting.
I’ll plug the Arc back in and cycle them again (my poor back lol)

I’m sorry. I’ve just realized I’m confusing your thread with another one I’ve recently posted in. And I owe @CrystalGipsy an apology.

Before you plug the Arc back in and reset everything again, you need to lower the max bit depth per sample to 16 under Device Setup for your Office (i.e., the Connect). See these screenshots for how it looks on one of my Play:1s.

That will make your signal path for that room look something similar to this:

I already set 16-bit before we started with the reboot cycles, but no luck. I’m now back on WM:0 for everything (except roam) with the Arc having the wire and still glitchy.

Oh, and I’ve got this in settings/audio now - odd that the two oldest bits of kit are the ones now showing up under Roon Tested.

That’s correct only S1 Sonos devices have past Roon tested status, no others have been submitted to Roon to test. Roon Tested status relies on the manufacturers to want to have it and submit to a Roon. It doesn’t mean they won’t work, I have no issues with my ARC but I don’t own any more Sonos zones than that.
