You will need a Plex Pass and remote access to play on Sonos - Plex is working with the current Sonos App build, as I’ve just tried it here. Also see this link:

Oh, that’s unfortunate Sonos can’t just read the contents like a DLNA client, but requires a paid subscription to Plex.  

Plex is a cool service, but not worth the price just for an API.

I have the Plex lifetime subscription and admittedly use it a lot when travelling, so it was worth it in my case. I like having the Plex App on TV’s, Tablet, Phone etc. Their interface is v/good too with the option to use Plex ‘connect’ to play on Sonos, or via the Sonos App. 

I would perhaps like to see the Plex interface on Sonos updated/refreshed now though, so it was perhaps similar to the Plex scheme, or at least aligned similar to some of the other Sonos MSP interfaces, like BBC Sounds or the Apple/Deezer music services. 

Anyhow Plex does seem to work extremely well with my local/remotely-accessible (NAS) Plex server, so the £80+ (discounted offer) that I paid, a year or two ago, for the lifetime access seems worthwhile. 

I too have a lifetime subscription to Plex Pass. It never worked very good on my 2010 QNAP, but on my 2020 QNAP it works good for music. I do miss a folder view in Plex on Sonos though.

You don’t need a Plex Pass, I’m using the free Plex version with Sonos without any issues.

Hi @wottynatty 

Thanks for your post!

I can confirm that @Outburst is correct - you don’t need a Plex Pass to play your Plex music library on Sonos.

It could be that you need to make sure that Online Access is enabled in your Plex server’s settings, as Sonos speakers access Plex libraries via the cloud.

I hope this helps.
