The “Won’t Release” problem persists. If my audio unit is turned on and playing a network source (via airplay); as soon as I start AS on my mini Mac, the audio unit is taken over by AS and all other sources are blocked. I can’t force the audio unit to play any other source as long as AS is running (not playing - just running). Unlock icon shows unlock !! As soon as I quit AS, the audio unit performs normally again. Audirvana V3.5.5 has NONE of these problems. If 3.5.5 is not playing, I can stream from any other network source with no problems. 3.5.5 can remain running - it does not cause control problems. What’s different with AS that causes these control problems??? I’ve been asking about this problem since Studio was released.
