Description of Issue

I have Core on MacMini with connected McIntosh MC2700 pre-amp via USB
When nothing plays in a while (~30min) McIntosh disappears from Roon Control as an Audio Device
I have to remotely log to Core on MacMini, click on “Select Audio Zone” , select McIntosh and after that it appears in my Control again
“Sleep” on MacMini is disabled:

What should I do to make pre-amp connected via USB always available?

Hi @Dmitriy_Kagarlickij,

When this issue occurs, is the McIntosh endpoint still visibile in your Audio Midi Setup utility (Applications → Utilities → Audio Midi Setup).

Do you experience this behavior with any other USB devices, whether audio or storage?
