To hear Atmos content with Apple Music, Apollo x16 must be set to 16 channels within its I/O Matrix. If Apollo x16 is set to anything other than 16 channels, Apple Music will playback audio in 5.1 instead of the desired Atmos format.
Note: After adjusting the I/O Matrix, Apple Music must be quit and reopened.
To adjust the Apollo x16 I/O Matrix, navigate to:
- UA Console > Console Settings > I/O Matrix > # Outputs drop down menu.
Then, select 16 channels in the drop down menu.
