How to Record Teams & Chrome Audio on macOS

Recording Teams, Chrome & Mic on macOS

Recording professional meetings or technical demos on a Mac is notoriously tricky because macOS doesn't allow internal audio capture by default. This guide shows you how to use BlackHole 2ch to route audio perfectly.

The Goal

Capture Teams audio, Chrome audio, and your Jabra Mic simultaneously while hearing everything through your headset.

Step 1: Create the "Ear" Device (Multi-Output)

This allows sound to play in your headset and go to the recorder at the same time.

• Open Audio MIDI Setup (Applications > Utilities).
• Click the + icon and select Create Multi-Output Device.
• Check BlackHole 2ch (First) and Jabra Headset (Second).
• Set Master Device to Jabra Headset.
• Check Drift Correction for BlackHole 2ch.

Step 2: Create the "Record" Device (Aggregate)

This merges your mic and system audio into one virtual stream.

• Click + and select Create Aggregate Device.
• Check BlackHole 2ch (Channels 1-2).
• Check Jabra Headset (Channel 3).
• Check Drift Correction for the Jabra.

Step 3: App Configuration

Application	Setting	Selection
macOS System Sound	Output	Multi-Output Device
Microsoft Teams	Speaker	Multi-Output Device
Microsoft Teams	Microphone	Jabra Headset (Direct)
Recording App (QuickTime)	Microphone Input	Aggregate Device

⚠️ Pro-Tip: The Volume Lock
macOS disables volume keys for Multi-Output devices. Set your Jabra volume to 100% before switching the system output to the Multi-Output device to ensure the recording isn't quiet.

Troubleshooting: Silent Recordings?

If your level meters aren't moving in QuickTime or Audio MIDI Setup, try the "Nuclear Reset":

Restart the Audio Engine:
Open Terminal and type: sudo killall coreaudiod.
This force-restarts the macOS audio daemon and usually clears any "clogged" virtual pipes.

Note: Always verify your settings in System Settings > Privacy > Microphone to ensure your recording app has permission to access the audio streams.
