AU Lab input now working on M1 Monterey

Hi,

I'm using MacBook Pro M1 2020. I noticed that AU Lab is not receiving any input signal. When I create a new document with the Built-in microphone set as input, no audio is being monitored. But when I open System Preferences -> Sound, I can see that the microphone is cathing some input signal. (Eventually, I'd like to use AU Lab with VB Cable as input.) I guess the problem might be connected with some Privacy settings, but AU Lab is not present in the Privacy-Microphone apps list. That means I can't give the app a premission. Anyone knows how to allow AU Lab to receive an input signal?

Thank you in advance.

I'm sorry, I didn't provide enough information. I tried different AU Lab versions from multiple Apple links. But the last one I found, which seems as the latest version, I downloaded from https://developer.apple.com/download/all/?q=au%20lab Here it is as a bundle of Additional Tools for Xcode 13.2.

I found the link https://discussions.apple.com/thread/8552731 earlier but the problem is I can't see the AU Lab app in the list of apps which ask for Microphone access permission. Thus I can't grant that permission.

Another links that I found but didn't work for me are:

https://discussions.apple.com/thread/251269841

https://discussions.apple.com/thread/4095261

https://github.com/ExistentialAudio/BlackHole/issues/4

If more information is needed, I'm willing to provide it.

Presumably this AU Lab app is what you're using: https://www.apple.com/ca/itunes/mastered-for-itunes/

There's mention of a possibly-related microphone-access issue here: https://discussions.apple.com/thread/8552731

If restarting into Safe Mode doesn’t clear this—the reboot and the cache rebuild can sometimes clear odd issues—then I suspect you’ll want to discuss this with Apple Support, both the bug / error / issue with microphone access directly here, and secondarily also the existence of multiple apparently-different download versions of this app scattered around Apple.

Same problem here with Macbook Air 2020 M1 and latest MacOs. Blackhole input works in Reaper but not in AU Lab. Frustrating because I use it a lot.

Thank you for the tip. I restarted into Safe Mode but unfortunately VB Cable didn't work properly. While running it's diagnostic tool, I discovered that the "Agent runnig" test failed. So probably some extension which is needed for VB cable wasn't loaded in the safe mode. I tried listening to VB Cable output with Reaper (DAW program) which went all right. So I guess there is really a problem in the AU Lab app. I'll contact the Apple Support.

Thank you very much for you time and advice.
