Stream music to multiple devices with Apple Music won't work

Hello EstefanB,

Let's see if we can clarify something.

If the devices meet the requirements listed here, Use AirPlay to stream audio – Apple Support, they can be used for simultaneous streaming:

Play audio on your iPhone, iPad or iPod touch with iOS 11.4 or later, or a Mac with macOS Catalina or later. Then use AirPlay to stream that audio to your AirPlay-compatible speakers or smart TVs.

To stream audio to multiple speakers with AirPlay 2, simply select multiple AirPlay 2-compatible speakers or smart TVs. To ask Siri to play a film or TV programme in the room you want to watch it, add your AirPlay 2-compatible speakers and smart TVs to a room in the Home app. 

Stream audio from an iOS or iPadOS device

Stream audio from Apple TV

Stream audio from Mac

Stream audio from your iPhone, iPad or iPod touch 

Play music on your iPhone, iPad or iPod touch, then control where it's playing from Control Centre:

1. Open Control Centre on your iPhone, iPod touch or iPad:

• On iPhone X or later, or iPad with iPadOS or later, swipe down from the top right-hand corner of the screen.

• On iPhone 8 or earlier, or iOS 11 or earlier, swipe up from the bottom edge of the screen.

2. Touch and hold the group of controls in the top right-hand corner, then tap AirPlay .

3. Tap each speaker or TV that you want to play the current audio on. 

You can also use AirPlay to stream audio from an app you're using on your device. Just open the app, tap AirPlay , then tap a speaker or multiple speakers.

The key requirement is that they be AirPlay 2 compatible.

Have a good day.

Hello EstefanB,

You've done a fantastic job explaining the issue.

However, as previously mentioned, Apple Music streaming is only supported on one output device at a time. The only exception is If you are using Apple Music with Family Sharing and have different Apple IDs. Then, you could stream on multiple devices, as explained further in the link you were previously provided.

Please do not hesitate to contact us if you have more questions.

Thanks for using the Apple Support Communities.

Cheers!

Hello EstefanB,

Apple Music streaming is only supported on one output device at a time. If you are using Apple Music with Family Sharing and you have different Apple IDs, you would be able to stream on multiple devices. This is explained further here: Get an Apple Music family subscription.

Let us know if we can help with anything else at all or if this doesn't settle your issue so we can look into this further with you. Thanks and have a fabulous day!
