Seems Blackhole doesn't work in MacBook with M3 MacOS: Version 15.1

[bingozh]

I installed the blackhole 16ch in my Mac book M3 MacOS: Version 15.1. It is installed successfully. But there is no audio output from the Multi-output device. Does anyone tried such OS before? What is wrong with my configuration? Thanks in advance.

Looks fine but I also have no idea what you are trying to do.

Thanks a lot for your reply. Previously, we can get the audio data from the virtal device BalckHole 16ch since it is a virtual microphone. But after upgrade the OS to 15.1 in my MacBook, I find that there is not any audio data out from the virtual micrphone of BlackHole as marked in the red box in below picture. How can I do the investigation where is the issue?

Try recording with audacity. Also any specific reason for 16ch? if not use 2ch. Devin

Thanks a lot for your reply. I want to use below code to get the audio data from the virtual micrphone according to the blackhole label:
const stream = await navigator.mediaDevices.getUserMedia({audio: {deviceId: mic.deviceId}});
The audio tracks in the stream is 1. But there is not any data out from the stream when I playing some audio. I remember that I tried this before and it worked at that time before my OS upgrade. So how can I know how to find out the issue here?

Sounds like a mic permission issue. Check that first.
