Note that the idea of exclusive mode doesn’t apply to all devices:
- “System Output” is never accessible in exclusive mode.
- ASIO and ALSA are always in exclusive mode, so there’s no setting to flip.
- The concept of “exclusive mode” doesn’t exist for hardware devices…squeezeboxes, sonos, Roon Ready, Meridian, AirPlay, etc.
