I ran into an interesting situation today. I decided to try my cobalt to play through my stereo system using a macbook pro. Tidal detected the dragonfly and automatically set it up to "exclusive mode", "locked volume", and not "pass through" mqa so it could do software unfolding and send it to the dragonfly. Now, I have to say at this point I am lucky the dragonfly was connected to the line-in of my stereo and not my IEMs. Because it was now essentially playing at full volume, the tidal volume control was locked to full volume as normally would be done to support MQA. And the volume control of the OS was not taking effect, maybe because of exclusive mode. I could not select the dragonfly and have a working volume slider. So anyone know what's going on here and how to safely have volume control on OSX while keeping full quality MQA output?
