How to Delete a Multi-Output Device on Your Mac: A Comprehensive Guide

Multi-Output Devices on macOS are incredibly useful for routing audio to multiple destinations simultaneously. Whether you’re trying to play music through your speakers and headphones at the same time, or sending audio to different recording devices, this feature offers immense flexibility. However, there are times when you might need to delete a multi-output device. Perhaps it’s no longer needed, is causing conflicts, or you simply want to clean up your audio settings. Whatever the reason, this comprehensive guide will walk you through the process of deleting a multi-output device on your Mac, providing detailed steps and explanations to ensure a smooth experience.

Understanding Multi-Output Devices on macOS

Before we dive into the deletion process, let’s briefly understand what a multi-output device is and how it works. In macOS, an audio device represents any hardware that can output sound, such as your built-in speakers, external headphones, or a USB audio interface. By default, only one audio device can be used for output at a time. Multi-output devices allow you to combine multiple physical audio devices into a single virtual device. This virtual device then acts as a single output point, simultaneously sending audio to all the included physical devices. This capability is extremely helpful for various scenarios, including:

• Multi-Speaker Setups: Playing audio across multiple speakers in different locations.
• Headphones and Speakers: Using headphones while still playing music on speakers for a group of people.
• Audio Recording: Simultaneously monitoring the audio output on your headphones while recording it to another device.
• Live Streaming: Routing audio to both your streaming software and external speakers/headphones.

Creating and using multi-output devices is simple, but as with any software feature, they might need to be managed and sometimes removed. Let’s now move on to the steps for deleting them.

Why Delete a Multi-Output Device?

There are several reasons why you might want to delete a multi-output device on your Mac:

• No Longer Needed: You might have created a multi-output device for a specific project or purpose, which is now complete. Removing it keeps your audio settings clean and organized.
• Conflicting Devices: Sometimes, changes in your audio setup or the introduction of new devices can cause conflicts with existing multi-output configurations. Deleting and recreating them can resolve these issues.
• Performance Issues: An improperly configured or corrupted multi-output device might lead to audio glitches, delays, or other performance problems. Deleting and recreating can often solve such issues.
• Simplifying Audio Setup: If you no longer require the complexity of a multi-output device, deleting it simplifies your audio routing and makes it easier to manage.
• Troubleshooting: When facing audio problems, deleting and reconfiguring the multi-output setup can help identify the source of the problem and ensure you’re starting from a clean slate.

Whatever your reason, the following steps will guide you through the process effectively.

Detailed Steps to Delete a Multi-Output Device on macOS

The process of deleting a multi-output device on a Mac is straightforward, but it requires accessing the Audio MIDI Setup utility. This is the central hub for managing audio and MIDI devices on macOS. Here’s how to do it:

Step 1: Access Audio MIDI Setup

1. Open Finder: Click on the Finder icon in your Dock. It looks like a blue and white smiling face.
2. Go to Applications: In the Finder window, click on “Applications” in the sidebar.
3. Open the Utilities Folder: Scroll through the list of Applications and find the “Utilities” folder. Open it.
4. Launch Audio MIDI Setup: Locate the “Audio MIDI Setup” application and double-click it to open. The icon looks like a black keyboard and a white speaker. Alternatively, you can use Spotlight Search by pressing Command + Space and typing “Audio MIDI Setup,” then pressing Enter.

The Audio MIDI Setup window will now appear, showcasing the various audio and MIDI devices connected to your Mac.

Step 2: Locate the Multi-Output Device

Once Audio MIDI Setup is open, you’ll need to locate the specific multi-output device you want to delete. Here’s how:

1. Select the Audio Devices Tab: In the Audio MIDI Setup window, make sure you have the “Audio Devices” tab selected. It’s usually the first tab on the top.
2. Identify the Multi-Output Device: On the left-hand side of the window, you’ll see a list of all available audio devices. Multi-output devices are typically listed under the “Multi-Output Device” section, and their names often indicate they are combined output devices. Look for the name you gave the device when you created it, or if you used the default name, it will typically be something like “Multi-Output Device.”

Take note of the exact name of the device you want to delete.

Step 3: Delete the Multi-Output Device

Now that you’ve located the device, you can proceed with the deletion:

1. Select the Device: Click on the name of the multi-output device you wish to delete. This should highlight it.
2. Click the Minus (-) Button: At the bottom of the device list, you’ll see a plus (+) and minus (-) button. Click the minus button. This removes the selected device.
3. Confirmation Prompt (Optional): In some versions of macOS, you might get a confirmation prompt asking if you are sure you want to delete the multi-output device. Confirm the deletion by clicking “Delete” or “OK.” This prompt isn’t always present but if it is, it’s best to double check that it’s the correct device.

After completing these steps, the selected multi-output device will be removed from your audio device list.

Step 4: Verify the Deletion

To ensure that the device has been successfully deleted, perform the following steps:

1. Check the Audio Devices List: Double-check the list of audio devices in the Audio MIDI Setup window to confirm that the multi-output device is no longer present.
2. Check System Audio Preferences: Go to your System Settings (or System Preferences on older macOS versions) and select “Sound.” Look at the “Output” tab and verify that the deleted multi-output device is also not listed there.

If the device is gone from both Audio MIDI Setup and the System Sound settings, you have successfully deleted the multi-output device.

Step 5: Close Audio MIDI Setup

Once you have verified the deletion, you can close the Audio MIDI Setup application by clicking the red “close” button in the top-left corner of the window.

Troubleshooting: What to do if you face problems
