Where Logic Pro sends your sound, and why it matters for security

Logic Pro defaults to sending audio through your computer's built-in speakers or headphones, but you can route it to any audio device connected to your Mac — an external interface, a USB microphone, studio monitors, or even a network device. Changing the output is a one-step process in the Audio/MIDI Settings menu, and you may need to do it if you've plugged in new hardware, switched between different recording setups, or want to isolate your work audio from your system audio.

From a security perspective, knowing which device is receiving your audio matters. If you're working with sensitive material — client recordings, confidential interviews, or personal content — you want to be certain the sound is going only where you intend. A misconfigured output could send audio to a network device, a Bluetooth speaker, or a USB hub you didn't realise was active. This guide walks you through finding and changing your output, and checking that your audio is going to the right place.

Key Takeaways

  • Open Logic Pro, then go to Logic Pro menu → Settings → Audio/MIDI to see all connected audio devices and choose your output.
  • Your current output device appears at the top of the Audio Devices list; click any other device to switch when ready.
  • If your desired device does not appear in the list, check that it is powered on, properly connected via USB or Thunderbolt, and recognised by your Mac's System Settings.
  • You can save different output configurations as separate projects or use the same project and switch outputs before recording or playback to match your workflow.
  • Bluetooth audio devices may take a few seconds to appear in Logic Pro after you pair them with your Mac; if they do not show up, unpair and re-pair the device.

Finding the audio output menu in Logic Pro

Start with Logic Pro open. At the top of your screen, click the Logic Pro menu (the one with the Logic Pro icon), then select Settings. A submenu will appear. Click Audio/MIDI.

A window titled "Audio/MIDI Settings" will open. On the left side, you will see a list of tabs. Make sure you are on the Devices tab — it is usually the default. The main panel on the right will show your Audio Devices list, with your current output device highlighted at the top.

If the Audio/MIDI Settings window does not open, or if you see a message that no audio devices are found, your Mac may not have recognised your audio hardware yet. Disconnect the device, wait 10 seconds, reconnect it, and try again. If it still does not appear, move to the troubleshooting section below.

Switching to a different audio output device

In the Audio Devices list, you will see all audio devices your Mac recognises. The device at the very top, with a small speaker icon next to it, is your current output. To switch to a different device, straightforward click on it once. Logic Pro will route all audio to that device when ready — no restart or confirmation needed.

Common output devices include your Mac's built-in speakers, external USB audio interfaces, Thunderbolt interfaces, USB microphones with headphone outputs, and Bluetooth speakers or headphones. Each device will show its name and connection type (USB, Thunderbolt, or Built-in). If you have multiple interfaces connected, they will all appear in this list.

After you switch outputs, play a short section of audio or a test tone to confirm sound is coming from the correct device. If you hear nothing, or if sound comes from the wrong place, check that the device is powered on and that its volume is turned up. Some external interfaces have their own volume controls on the hardware itself.

What to do if your audio device is not showing up

If the device you want to use does not appear in the Audio Devices list, the problem is usually one of three things: the device is not powered on, the connection is loose, or your Mac has not yet recognised it.

For USB or Thunderbolt devices: Unplug the cable from your Mac, wait 10 seconds, and plug it back in. Open Audio/MIDI Settings again. If the device still does not appear, try a different USB or Thunderbolt port on your Mac. Some ports are faster or more stable than others. If you are using a USB hub, try plugging the device directly into your Mac instead — hubs can sometimes prevent recognition.

For Bluetooth devices: Make sure the device is powered on and in pairing mode. On your Mac, go to System Settings → Bluetooth, and check that the device is listed and connected. If it is not paired, click "Pair" and follow the on-screen steps. Once it is paired and connected in System Settings, it should appear in Logic Pro's Audio Devices list within a few seconds. If it does not, close and reopen the Audio/MIDI Settings window.

For built-in audio: If your Mac's built-in speakers or headphone jack is not showing up, go to System Settings → Sound and check that the device is not muted or disabled. You can also restart Logic Pro to refresh the device list.

Checking your output before recording or streaming

Before you record or stream audio from Logic Pro, take 30 seconds to verify that your output is set correctly. Open Audio/MIDI Settings, look at the device shown at the top of the Audio Devices list, and confirm it is the one you want. This is especially important if you have multiple audio interfaces or if you switch between different setups — a wrong output choice can send your work to the wrong place or to a device you did not intend to use.

If you are recording a podcast, interview, or other content that will be shared, you may want to route your output to headphones or studio monitors so you can hear yourself clearly, while your recording goes to a separate track or interface. Logic Pro lets you do this by setting your output device and then choosing your recording input separately in the same Audio/MIDI Settings window — look for the Input Device section below the Output Device section.

Some users create separate Logic Pro projects for different workflows — one project with output set to headphones, another with output set to studio monitors. This way, you can open the project that matches your current setup without having to change settings each time.

Saving and switching between output configurations

Logic Pro does not have a built-in preset system for output configurations, but you can work around this by saving your project with a specific output setting. When you open that project again, Logic Pro will remember which output device you chose last time — as long as that device is still connected to your Mac.

If you frequently switch between two setups (for example, headphones at home and studio monitors at work), consider naming your projects to reflect the output: "Podcast_Monitors" and "Podcast_Headphones". When you open the project, the output will be set to what you chose before. If the device is not connected, Logic Pro will fall back to your Mac's default output, so always check the Audio/MIDI Settings window before you start working.

Another approach is to use Logic Pro's Environment window to create custom output routings, but that is an advanced technique. For most users, straightforward switching the output device in Audio/MIDI Settings before each session is the simplest and most reliable method.

Frequently Asked Questions

Can I send different tracks to different output devices at the same time?

Not directly through the output device selector. Logic Pro sends all audio to one output device at a time. However, you can use the Environment window or create separate auxiliary channels routed to different outputs if your audio interface supports multiple outputs. This requires more advanced setup, so start by checking your interface's documentation.

Why does my audio device disappear from the list when I unplug it?

Logic Pro only shows devices that are currently connected to your Mac. When you unplug a USB or Thunderbolt device, it is no longer available, so it disappears from the list. Plug it back in, and it will reappear within a few seconds. Bluetooth devices may take a bit longer to reconnect.

What happens if I change the output while audio is playing?

Logic Pro will switch the output when ready, and playback will continue through the new device without stopping. This is useful for testing different outputs, but it can be jarring if you are not expecting it. Always check your output setting before you press play if you want to avoid surprises.

Can I use my Mac's built-in speakers and an external interface at the same time?

No. Logic Pro routes all audio to one output device at a time. You can switch between them, but not send audio to both simultaneously. If you want to monitor through headphones while recording through an interface, set your output to the headphones and your input to the interface, then record.

Why is my Bluetooth speaker connected to my Mac but not showing up in Logic Pro?

Bluetooth devices sometimes take a few seconds to appear in Logic Pro after they connect to your Mac. Close the Audio/MIDI Settings window and reopen it. If the device still does not appear, unpair it from your Mac in System Settings → Bluetooth, then pair it again and wait 10 seconds before opening Audio/MIDI Settings.
