@Dave7 - I am a total Apple refusnik. I have always avoided their products. But I don't think they decided to remove the feature from Sonos and they cannot decide to reinstate it.

Apple made changes to iOS that had the (probably unforeseen) consequence that 'on this iPhone' became unreliable for many users.

I am the last person to defend Apple but I think your presentation of what happened here is wide of the mark.

I am in agreement with John. This is most likely a by-blow that occurred as a change that was made for entirely other reasons then messing with Sonos and BlueSound, and any other company who was using the same method to use iOS as an NAS device. Quite likely either a power concern, or battery concern, but it’s hard to think that Apple was targeting anyone in particular. 

John B and Airjetlam, I appreciate your comments, and i do not know Apple’s motive (OS incompatibility or business strategy) for removing support of this feature. However programmatically this seems a basic task - making audio files available to the Sonos app for relatively low bandwidth streaming. Airplay does that. So, I’m highly sceptical. Regardless, their action has made their products incompatible with our music systems so my position is still relevant. And I understand reluctance on Apple products - the philosophy of locking everything down is hard to swallow, but the upside is most things work well.

In fact 'on this iPhone' worked very differently from Airplay and I suspect that goes to the hesrt of the issue. But none of us knows for sure exactly what happened and so let's agree to differ. The end result isn't going to change.

This extremely disappointing news.

This is the sole reason I purchased over 30 products from Sonos!

This is the only way I use the system.

This was an advertised feature...and the sole reason for purchase. 

While the EULA may allow for changes - this is a broken deal by any stretch.  

I would read the EULA you agreed to before making such demands.

With the feature gone for several months now, you don’t seem to use your 30 speakers very much?

Also claims to own an Amp and Play:5 Gen 2, which are both Airplay capable.  

Just brainstorming here, but it's possible the poster didn't update until now. There's been numerous posts here that it's still working on older versions. 

Airplay 2 on Sonos isn't that good compared to say Homepod (ime). The loss of one feature doesn't mean owners will be happy with a new feature that in their use is inferior to the deleted feature.

This is actually ridiculous.

I listen to music that I have ripped from CDs that I have purchased legally, and those songs are NOT available on any streaming service I can guarantee that.

I have an iphone 6 and a really old sonos (its not even mine so I dont know what type it is)

So now it just means I wont be buying your product when it's time to upgrade if I cant listen to the music I want to.

Welcome to the forum  Have you been away from home for a few months?

If only there was a way to store these CDs on a computer drive, or a USB drive, or an NAS device, or a free-to-own music storage account with a company like Google… and then choose to stream from that storage medium. Then you could play your own music tracks through your Sonos speakers. 

This sounds fake and contrived to me.

Don’t want to sound like a total noob, but all the info i have gathered so far just didn’t clear up a very simple question.

I want to buy One SL, but the title of this thread makes me think that i won’t be able to stream the music i have in my iOS Music App (sync’d from my personal iTunes library; yes, i don’t use any streaming services, i like to OWN my music). Am i wrong? I hope so!

The One SL supports Airplay 2 so you’re fine with it/them. 

If the library is on a computer hard drive you can set that up as a Music Library and play from that. 

So i would have an access to my whole music library via iPhone, not just the stuff i have sync’d, right? But you don’t actually upload anything to some Sonos server doing that - meaning i have to be within my Wi-Fi network, correct? And this option requires a Sonos App as a player, not iOS Music App? 

There is no “Sonos” server to upload to. If your phone is on the same Wi-Fi subnet as your Sonos One SL, you’ll be able to use AirPlay 2 to connect to it, in which case any sound coming from an AirPlay 2 app (there are a small few that aren’t, no I can’t point to a list) will play on your Sonos. 
 

In the case of using AirPlay 2, you would be using the Apple Music app, and not the Sonos app, although you could, if you so choose, use the Sonos app to group several Sonos rooms together so they all play the sound you’re sending to the Sonos One SL.

Ok, thank you for answering my questions guys. AirPlay 2 and “On this phone” appear to be totally different ways to stream, right? I can stream to my One SL - just not with the “On this phone” option, but via AirPlay 2. I guess i just confused these things with each other, i thought Sonos have totally “banned” access to the personal music leaving streaming services as the only option.

Sonos speakers incorporate (in effect) a computer and network interface. The IOS, Android, MAC or PC controllers are just that: devices to initiate play and volume of a music source - a Spotify stream or whatever. You can also set a path to a networked computer location music library where you have ripped your CDs. There is an approximately 64000 track limit.

So, your phone is a controller, to tell the Sonos “computer” what music you want it to play. But, with Airplay 2, the music can also be sent from phone to Sonos. 

But, you will need to be on the local network for your phone, Mac or PC to be the controller. 

Yes, they are two completely different things. AirPlay 2 “pushes” the audio content from your iPhone to the speakers. The Sonos system “pulled” the data from the iPhone, treating it as an NAS, not a player. Apple closed that functionality for some unexplained reason, so Sonos, and at least one other company can no longer use that method to get music. 
 

In fact, that is one of the central design things about Sonos. In most cases, you tell the computer on the speaker where to access the music from, it is never “playing” on the controller. 

Love the thread here… Like our whole family is going to move to Android because of that. Or start subscribing to music streaming service to make use of our 8 speakers. What a load of crap. Goodbye Sonos, you are now  useless to me.

Read the options and you’ll see you’ve missed several of the ones available to you.

You need not subscribe to any paid service to play your music. 
You need not stream other than from your own network environment. 
 

We have been streaming from a Mac too, but that is not an option to me going forward. I just need to do it from my phone. Anyways, I see this is one of these silly situations where Sonos and their minions are going to explain why this is a good change for me. Bye Sonos, have fun retaining new customers you may get.

@PLPL For people affected by this the user experience is worse after this - no question.

You however are not seriously affected: you own a One (or more of them) according to your account, that is Airplay 2-capable.
