Move cuts in & out when grouped with Arc to listen to TV

Already tried.

Ah. I missed that this had already been attempted. 

There is something odd going on here if the sound is cutting out wherever you place the Move and however large the group audio delay.

Please tell us about your network. Make and model of router? Mesh WiFi? Any other Sonos besides that mentioned? Any Sonos device wired?

If the Move is connected to your routers 5Ghz WiFi band, then try switching it over to the 2.4Ghz Wifi band, which is likely what your old Play:5 would have used. Also set that band to use a ‘fixed’ non-overlapping WiFi channel, either channel 1, 6 or 11 and if your router allows set the channel-with to 20Mhz only rather than the usual 20/40Mhz that many routers seem to use these days.

See if those few quick adjustments resolve your audio dropout issues.

We have a Telstra Smart modem.

Our Sonos system is on our 2.4Ghz band and I have it fixed on channel 11 and 20Mhz.

Within our Sonos system we have the Arc, sub, plus two Play 1’s connected to our main TV as our home theatre setup. We also have in another room our older Playbar connected to another TV. Plus we have the Move.

We used to have a Bridge connected directly to our router however Bridges no longer work on the new Sonos app so had disconnected that. We therefore do not have any Sonos wired to the router.

@jujiba,

I am wondering if it’s this one🤔?…

Gen 2, but why would it be the router if sound works fine when we are listening to music and grouping the Arc system and our Move?

Just some of the user comments seemed to infer the gen3 wasn’t all that wonderful and there was mention of issues with Bose speakers. A bit flaky by all accounts, so if it was your device, I would have perhaps suggested trying something else in its place, in case there was a compatibility issue with some WiFi adapter hardware and to see if things then improved for you.

@jujiba,

I have a Sonos Arc here with surrounds and sub and have grouped it with our Sonos Move and apart from the usual delay related to ‘group buffering’, it plays the TV audio fine, even with the Arc buffer set to its least setting of 75ms and it doesn’t dropout at all.

Admittedly I use the two rooms mentioned (Arc/Move) more, in fact regularly, to play music audio (in sync) and the Move never drops its connection .. so something is wrong somewhere, whether that is your Move, Arc or the WiFi network in-between, so it’s worth exploring each of those elements. It just happens when I searched for the Telstra product there were some negative reviews in regards to that brand/model.

I’ve briefly gone back to (re)search the gen2 model and seeing reports on band-steering, but not had a chance to fully read those, as it’s late where I am, but it might be worth perhaps digging further into that aspect.

I experimentally grouped my Move, which by default resides in the kitchen to my living room Playbar for half an hour then to my media room Arc. Played TV sound fine in both cases. Brief experiment and the Move is not far from the router, but I really don't think there is a generic problem with the Move.
