MusicKit: Multichannel Dolby Atmos Limited to Stereo Output - Is This Intended Behavior?

I'm experiencing a significant limitation with MusicKit's Dolby Atmos implementation on macOS and would appreciate clarification on whether this is intended behavior or if there are solutions available.

When streaming Dolby Atmos content through MusicKit's ApplicationMusicPlayer, the output is limited to 2-channel stereo, even when:

  • Audio MIDI Setup is configured for 7.1.4 (12-channel) output
  • The same tracks play in full multichannel through the native Apple Music app
  • Dolby Atmos is set to "Automatic" in Apple Music preferences

Please let me know if there is anyway to enable this. If not, is this documented anywhere? Thanks!

Anyone able to provide guidance on this one?
