Where to Find Audio Output Settings on Mac

Open System Settings (called System Preferences on older Macs) and go to Sound. You will see three tabs: Input, Output, and Effects. Click the Output tab to see all devices your Mac can send sound to right now.

The Output tab shows every audio device connected to your Mac — built-in speakers, external speakers, headphones, AirPods, USB audio interfaces, and Bluetooth devices all appear here. The device with a checkmark next to it is your current output. Click any other device to switch to it when ready.

If you do not see a device you just plugged in, wait five seconds for your Mac to detect it, then look again. If it still does not appear, unplug it and plug it back in, or restart your Mac if the device uses Bluetooth.

Key Takeaways

  • Audio output settings live in System Settings under Sound, in the Output tab, where you click the device you want to use.
  • Your Mac detects most wired audio devices when ready, but Bluetooth devices may take a few seconds or require you to pair them first in Bluetooth settings.
  • You can set a default output device so your Mac remembers your choice between restarts, or switch on the fly for one app only.
  • If sound comes from the wrong speaker or no sound plays at all, check that the correct device is selected and that its volume slider is not at zero.

Switching Between Speakers, Headphones, and External Devices

The fastest way to switch output is through the Control Center in the top-right corner of your screen. Click the sound icon (it looks like a speaker), and a menu drops down showing your current output device and a list of others you can switch to. Click any device name to send audio there when ready.

This method works for any audio device: your Mac's built-in speakers, wired headphones plugged into USB-C or a USB adapter, external speakers connected by cable or Bluetooth, AirPods, or a Bluetooth speaker. The device you select becomes active right away, even if an app is playing sound.

If you use the same output device most of the time, you can set it as your default in System Settings. Go to Sound, Output tab, select your device, and your Mac will use it automatically when you restart or when no other device is connected.

Connecting Bluetooth Audio Devices

Before a Bluetooth speaker, headphones, or earbuds can appear in your audio output list, your Mac must pair with it. Open System Settings, go to Bluetooth, and make sure Bluetooth is on. Put your audio device into pairing mode (usually by holding a button for three to five seconds — check the device manual), and it will appear in the list under "Other Devices."

Click Connect next to the device name. Your Mac will pair with it and remember it from then on. Once paired, the device appears in your Sound output list and in Control Center, and you can switch to it anytime without pairing again.

If a Bluetooth device was paired with another computer or phone, it may not pair with your Mac until you unpair it from the other device first. If pairing fails, restart both your Mac and the audio device, put the device back into pairing mode, and try again.

Fixing Sound That Comes From the Wrong Speaker

If sound is playing but coming from a speaker you did not choose, open Control Center and check which device is selected. The checkmark shows your current output. If it is wrong, click the device you want.

If the correct device is selected but sound still comes from somewhere else, the device may not be working. Go to System Settings, Sound, Output tab, and look at the volume slider for your selected device. If it is at zero, drag it to the right. If the slider is already up and sound still does not play, try unplugging and replugging the device, or restarting your Mac.

For Bluetooth devices, check that they are charged and within range of your Mac. If a Bluetooth speaker or headphones are too far away or have a low battery, your Mac may drop the connection and fall back to built-in speakers without warning.

Changing Output for One App Only

Mac does not have a built-in way to send one app's audio to a different device than others — if you set an output device, all apps use it. However, you can use a workaround: open the app, start playing audio, then switch the output device in Control Center. The app will send its sound to the new device while other apps continue using the previous one.

If you need this setup permanently, third-party apps like SoundSource or Audio Hijack let you route individual apps to different outputs. These are paid tools, but they offer a free trial so you can test whether they solve your problem before buying.

Troubleshooting When No Audio Devices Appear

If you plug in a USB audio interface, external speaker, or headphones and it does not show up in the Output tab, first check that the device is powered on and plugged in firmly. Wait ten seconds, then go back to System Settings, Sound, Output and look again.

If the device still does not appear, restart your Mac. Some audio devices need a restart to be recognized. If restarting does not work, the device may need a driver — check the manufacturer's website to see if they offer Mac drivers and install them if available.

For Bluetooth devices that do not appear, make sure Bluetooth is turned on in System Settings. If the device was paired before but no longer appears, go to Bluetooth settings, find the device in the list, click the X or "Forget" button next to it, then pair it again from scratch.

Understanding Volume Control and Output Quality

The volume slider in the Sound, Output tab controls the overall volume for your selected device. Dragging it to the right makes sound louder; dragging it to the left makes it quieter. If you mute your Mac (by pressing the mute key or using Control Center), all audio stops regardless of which device is selected.

Some external audio devices have their own volume control separate from your Mac's slider. If you turn up the Mac's volume but sound is still quiet, check the device itself — it may have a physical knob, button, or app that controls its own volume independently.

The quality of audio depends on the device, not on which output you choose. A Bluetooth speaker will sound the same whether you switch to it from Control Center or System Settings. Wired headphones plugged into a USB-C port will sound the same as those plugged into a USB adapter.

Frequently Asked Questions

Why does my Mac keep switching back to built-in speakers?

Your Mac may drop a Bluetooth connection if the device moves out of range, runs out of battery, or is turned off. Wired devices sometimes disconnect if the cable is loose or damaged. Check that your device is powered on, close to your Mac, and fully plugged in. If it keeps disconnecting, try a different cable or restart both devices.

Can I use two audio outputs at the same time?

Not through the standard Sound settings — your Mac sends audio to one device at a time. To play sound on multiple speakers simultaneously, you can create an Aggregate Device in Audio MIDI Setup (in Applications, Utilities folder), but this is a technical process. For most people, a Bluetooth speaker that can pair with multiple devices is simpler.

What if my headphones are plugged in but the Mac still uses speakers?

Open Control Center and check the Sound menu. If your headphones do not appear in the list, your Mac may not recognize them. Try unplugging and replugging them, waiting ten seconds, then checking again. If they still do not appear, restart your Mac. If the headphones do appear but are not selected, click them to switch to them.

Do I need to restart my Mac every time I switch audio devices?

No. You can switch between devices when ready using Control Center or the Sound settings without restarting. Your Mac remembers paired Bluetooth devices and will reconnect to them automatically when they are in range.

Why is there no sound from my USB audio interface?

Check that the interface is powered on and plugged in firmly. Go to System Settings, Sound, Output, and confirm the interface is selected. If the volume slider is at zero, drag it up. If the interface does not appear in the list, it may need a driver from the manufacturer's website, or your Mac may need a restart to recognize it.
