replyHmmm. What other cars have you tried? I wonder if it’s the DSP path used for CarPlay. Or could it be the Audi system is clipping this source? I’d find it really surprising if Apple is doing something here.
replyHave you tried Android Auto?
Maybe it’s trying to split the output into more than two audio channels when in CarPlay mode? If it were only Apple Music doing this I’d be sure this was triggering its Atmos output, not sure how it’d be affecting other players, but maybe.
replyTried every conceivable player, Spotify, YouTube Music, YouTube, Apple Music (local files), Soundcloud and more, all of them leading to the same thing, via USB+CarPlay the sound get normalized somehow but if using AUX/Bluetooth, works normally.

I hope so, most of what I play is stereo, and works fine via AUX/Bluetooth.
