Hi @Mark_Johnson , here’s a section from the Dorico FAQ:
Mac:
On macOS, AirPods and Bluetooth headsets easily bring Dorico’s audio engine into trouble due to the low spec built-in microphone. So here is the recommended way of dealing with them on Mac:
- Stop Dorico
- Make sure that the AirPods or Bluetooth headset is working with other apps, e.g. Apple Music.
- Launch Applications/Utilities/Audio MIDI Setup
- On the Audio Devices page create a new Aggregate Device
- In that device let only the stereo outputs of the AirPods or Bluetooth headset participate, nothing else
- Optionally, rename that device to your liking
- (In case of need, here is a more detailed article on how to create an aggregate device.)
- Start Dorico and go to Edit > Device Setup
- In the list of ASIO drivers your newly-created aggregate device shall turn up now. Select it, close the dialog, done.
- Don’t get tempted to select the other AirPods or Bluetooth headset related entries in the ASIO driver list: you might end up with situations where only the left audio will play out and it’s difficult to recover from that.
