I’ve had the Arc for over a year and not had this problem until this week. I play a particular track on Apple Music, through an Apple TV, on my Arc and I get a distortion when the music and singer hit a certain volume. It’s an album I’ve “added” to Apple Music (I have the iTunes Match service) but it encoded correctly.
I’ve played this same track on my Sonos One in the kitchen - no distortion.
Tried a couple of tracks from other albums I’ve recently added - same issue. Music directly from Apple Music seem okay.
Any ideas ?
