In some cases, you may want to send audio from your Mac to more than one speaker.For example, having several well-placed Bluetooth speakers around the house will fill the room with your music during a social gathering.Or maybe two people want to watch a movie with different headphones.
Whatever your reason for wanting to spread sound around, Apple makes it possible with one simple tool.Next, let's take a look at how to play audio from your Mac through multiple speakers.
How to Create a Multiple Output Device on a Mac
If you want to send audio to multiple AirPods, headphones, or speakers in macOS, you'll need to create a multi-output device in the Audio MIDI Setup app.Thankfully, the process is fairly straightforward.
To play audio through multiple devices on your Mac, first connect all audio output devices to your Mac.Then start the Audio MIDI Setup application.You can find the app in Applications > Utilities, or search via Spotlight.
Now click the plus (+) button in the lower left corner and select Create Multiple Output Device.
Check all the devices you want to add.If you don't see your device here, make sure it's successfully connected to your Mac.
Finally click the sound icon in the menu bar, or go to System Preferences > Sound > Output and select Multiple Output Devices.
When you enable multi-output mode, you lose the ability to change the volume using buttons or standard OS controls on your Mac.However, when you select a device in the Audio MIDI Settings side menu, you'll see a slider labeled Primary that you can use to adjust the volume individually.Alternatively, you can use the volume controls on the device itself, if available.
If you want to rename your multi-output device, you can do so by clicking the current name in the side menu and entering another name.
Audio MIDI Setup is a useful macOS tool
Often, some of macOS's most useful features aren't front and center.If you don't dig into the settings or explore every built-in app, you probably don't know exactly what the Mac OS does.
The Audio MIDI Setup app is an unsung hero that gives you more control over your hearing gear and can also help with stubborn sound issues.If at first macOS seems to be missing a key feature, you should dig deeper, as the solution may be just below the surface.
