Help with Mac Audio...not Audition specific

My Mac is hanging when attempting to open any audio app.

When attempting to open any Audio app on my Mac, i’m getting very long stalls.

Audition stalls at “Initializing (AUui)” but will load after about five minutes.

Reaper stalls at “creating Midi client”...I haven’t waited to see if it eventually opens.

GarageBand opens, but reports “Error initializing CoreMidi” and warns “MIdi Services not available.”

and the Apple Midi Setup stalls when Window>Show Midi Studio is chosen.

 

I’ve cleared any caches I could find, deleted prefs, and replaced my Library/Audio folder with a TimeMachine backup, but the issue persists. I’ve unplugged my vocaster and my Korg nanoKontrol and deleted midi drivers.

 

Any tips?

Apple M2 Max,  OS 15.7.1

    Bit of a false alarm:

    Looks like a hardware peripheral...unplugging everything allows Audition to operate. Now to re-plug one by one and find the culprit. I suspect a hub.

    If it’s an external one, my experience has been that they behave better when they are externally powered, although this might not be such an issue with USB-C hubs (generally more power available from the bus connection itself).

    Thanks Steve...my hub is old, and _not_ externally powered. Time for a new one, I suspect.
