So, updated my Mac mini M1 today. I can finally choose 8 ch 24-bit(192.0 kHz) for output. Joy! HDMI output is no longer locked at 24\/48. But, selected output is locked for everything. I use LosslessSwitcher app to match sample rate for output.\n\nSadly, still no Dolby Vision or Dolby Atmos in the Mac mini M1. I’ll still need to use the Apple TV 4K for proper playback of Apple Music Dolby Atmos tracks and also for movie in Dolby Vision and Dolby Atmos.
