Playback latency: Playhead delayed compared to audio

Hi,

I am using Dorico 5.1.30 on macOS with an Apogee Duet USB audio interface.

I’m experiencing a persistent problem: the playhead is slightly delayed compared to the audio playback.

I have tried:

Reducing buffer size (down to 128 samples)

Resetting the Audio Engine

Switching to Built-in Output instead of external interface

Resetting Playback Template

The issue persists across different projects, even new blank ones.

Sample rate is 48000 Hz. No NotePerformer is used.

Any help or workaround would be highly appreciated.

Thanks!
