I suspected it might be sample rate conflicts between audio programs, but that doesn't seem to be the case. It can happen any time but is infrequent, perhaps once or twice a week during near-constant use daily. Has anyone else experienced this with their Duet 3? I've been going back and forth with Apogee Tech Support and they have been very helpful, but we still haven't managed to figure out what is causing the noise. It happens most often when using Adobe programs simultaneously, like After Effects or Photoshop, but this could just be coincidence too as I use them most for work while listening to music. I don't recall hearing it happen in Logic, but it has happened in Apple Music (streaming or playing files on disk), Spotify and YouTube during playback. Unfortunately I'm having some issues with random bursts of digital noise (a high pitched beep lasting 1-2 seconds) during music playback. I bought an Apogee Duet 3 a few months ago and love the sound of it, it's a great unit and a long-overdue upgrade from the trusty old Apogee Duet Firewire I used for 12 years.
