Max number of tracks in a Spotify playlist

Yes, it would be the group coordinator. 

A Sonos One is a good device. I’d double check to ensure that you’ve assigned it a reserved IP address, since it’s wired, that’s pretty much the only possibility for network congestion. You’re looking at anything that might interrupt that 15 second time limit, IMHO. That’s the most likely one for a wired device.

Given the router, it’s not uncommon for the process of a Sonos software update to cause the router to hand out a duplicate IP address, but it’s up to the network as to how frequently that interruption can occur, too. 

There’s the temporary solution for duplicate IP addresses, which is unplugging all Sonos devices from power, then rebooting the router. Once the router comes back up, plug back in the Sonos devices. The challenge here is that if the router has failed in this fashion once, it could again, depending. The more permanent version of this is setting up reserved IP addresses in the router’s DHCP table, something that’s fairly easy to do, once you’ve read the router’s manual. Took me 5 minutes to understand how to do it for the first Sonos device, but after that, it was about 30 seconds per, and I did it for all of my network devices, and allowed some “headroom” for guests (technically, basement room….started all my Sonos stuff at .100, left everything below for random connections).

But @ratty has much more intimate knowledge in this area than I do, and a wider experience in networking across the board. Pay much more close attention to his comments than mine. 

@dan37,

If you want to make the playlist public (temporarily) and post it’s URL here, we can perhaps give it a try and see if we can load all its tracks on our own devices... I’m just not sure if we are able to access that with a free Spotify account, but if so I’m happy to give that a try or PM the URL to me, whichever you prefer.

@Airgetlam 

Thank you. However, I already use static IP addresses for all my devices. I looked at the table of currently attached devices and there are no duplicate IP address assigned.

@Ken_Griffiths 

Thank you as well. Here’s a link to a playlist that is timing out. I have temporarily made it a public playlist.

There may be some misunderstanding. The Group Coordinator is not the first room alphabetically, nor the first device that was originally installed. 

The GC is in the first room in any group -- to which other rooms are added -- and relates only to that specific group. Its job is to fetch the stream and distribute it to the other group members. As such its location is dynamic, depending on the composition of the group, and of course there will be multiple GCs if there are multiple groups. 

@ratty can you confirm my understanding that the GC, in sonosnet, will then route its requests to retrieve data via a wired component. And therefore the quality of that link matters well.

Yes. That’s its connection to the outside world. You may wish to refer to the Network Matrix at http://IP_of_a_player:1400/support/review to determine the active link and its signal strength.

I have Spotify Premium.

I’ve tried adding the 4k Spotify playlist to Sonos multiple times and get the queue error after 9secs.

Thanks @Mr. T - sadly I can’t assist further without subscribing, but maybe one or two others here will be able to check it too.👍

I assume the metadata in the playlist is too great given that I receive the queue error after circa 9 secs.
