Use ROAM or MOVE as Bridge from Bluetooth Turntable

@Erasers, 

How many other speakers are you grouping with the Roam? I appreciate you have tried different WiFi channels, but maybe also try the following…

• Set the 2.4Ghz band on your router to use a channel-width of 20MHz and if that doesn’t improve things maybe try…
• Wiring just one of the other ‘grouped’ speakers to your Router - that will switchover your main Sonos system to use SonosNet (let the system settle for 10 minutes after doing this) and then goto "Settings/System/Network” and set the SonosNet channel so it is at least 5 channels away from your chosen Router channel. So if you have set your router to use channel 6 (just as an example) then set your SonosNet channel to either 1 or 11. 

Perhaps see if doing either or both of these suggestions improves things for you.🤞

If you do the second bullet point, make sure you ‘start’ the group and playback from the wired speaker, which forces it to be the ‘group coordinator’ for that stream.

Thanks for the quick responses guys!

The bandwidths were already set to 20Mhz, so I didn't pursue that suggestion.

As a test, I set up a single play:1 speaker wired to my router which is upstairs from the Bluetooth setup. I then set the SonosNet to channel 11 and my router to channel 1.  Tried again and let it run for 10 minutes, still no better though.

I'm starting to think it's a wifi signal strength issue.  Never had an issue with other wifi devices downstairs, but I guess other playback mediums would buffer more?

Next test I'll buy a long cat5 cable and run it downstairs to see if the sonosnet runs smoothly from there.   I assume it emits from the play:1, right?

How do things work if you set aside bluetooth and just use an audio source from the Sonos App to play to the exact same group? I’m just wondering if it’s the device sending the Bluetooth audio that’s not managing to keep up - maybe also try bringing the BT device closer to the Roam (within 3 feet) and try another device (if possible) that may save you running lengthy cables, which may not make any difference anyway. So maybe try other things before resorting to that option.

@Ken_Griffiths  Great suggestion!  Ok so, the roam has throughout this process been inches from the Bluetooth turntable that I'm trying to get working, so I don't think that's the issue.  For your other troubleshooting question, I disconnected my phone from wifi and streamed music to the roam, which ran smoothly.  Then used another phone to bridge from the roam to my beam over Wi-Fi and had skipping again.

So I'm thinking it's the WiFi connection, going to try bridging over SonosNet all in the same room tomorrow with a long cable, will let you know how that goes.

@Ken_Griffiths shoot, so the cable SonosNet solution didn't work.  How do I know if it's creating the SonosNet though?  Wondering if I'm missing a step there beyond just plugging in the network cable and adding it to the Roams group.

I did a speed test on the 2.4G network and it's running at about 62mbps, while the wired is running at 94, should be lots for music.

Im at a bit of a loss here currently, any thoughts?

@Erasers, 

If you put the Roam in WiFi mode instead of Bluetooth and group it with your speakers does that play okay with a different playing audio source? How many speakers/Sonos Rooms are you grouping with the Roam?

Have you tried sending Bluetooth audio from a mobile device, rather than the turntable my thoughts are the turntable audio is having a hard time keeping up - you may have to try the TT using a line-in device instead of Bluetooth, perhaps, as that way there are different audio buffer sizes you can set, which are not available to you via a Bluetooth connection.

@Ken_Griffiths I've just been grouping with one other speaker (play:1).

When I play audio purely over wifi, starting with the roam, no issues.

When I play audio from a different Bluetooth source (my mobile) and bridge to the same speaker it still skips.  So this makes me think it's not the TT.

Should I be grouping more speakers for my tests?  What's the difference between a 'group' and a 'room' from a network perspective?

A ‘room is one of these, with or without Sub:

(1) A stand-alone speaker 

(2) A (stereo) ‘pair’ of speakers 

(3) A bonded HT setup 

A ‘group’ is where you play the same stream to more than one ‘room’.

If I ‘group’ my kitchen, 2 ‘pairs’ of Sonos Ones with a Roam, then that’s 3 Rooms grouped, but 5 speakers in total and I can stream Bluetooth to that group from my iPad Pro with no noticeable issues, but I don’t have a TT to test here .. My Kitchen is 12 feet square and there’s a speaker in each corner and the Roam sits on a worktop in the middle of the room next to the iPad, but I am running all on my WiFi setup rather than SonosNet.

I understand you have tried both WiFi and SonosNet that’s what made me think it might be your turntable, but if it’s  the same with other audio sources, then it might be interference, so perhaps try different SonosNet and/or WiFi channels using non-overlapping channels 1, 6 or 11. Ensuring the same channels are not being used by both your WiFi and SonosNet.

Hope that helps.

To provide some closure to this thread for anyone following along later.  I've deduced that the issue was largely due to strength of wifi signal to the Roam.  

The Bluetooth connection appears to be quite strong between the roam and the turntable as long as line of sight is maintained, as I moved the roam around my apartment, the skipping issue occured more frequently in areas further from the router.

Keep in mind I have other Sonos speakers in many of these areas which work fine for other music streaming, but for whatever reason the roam isn't great at it when bridging.

So, I've got the roam on the other side of the room now, much improved, still occasional skips.   Will probably attempt to fine tune with router settings etc to try and get it perfect at some point here.
