BlackHole 2ch greyed out in Audio MIDI Setup (followed all steps of wiki)

[rohanredtj]

The issue started a while back, where system audio is not being captured. I reinstalled the Blackhole, but still not working.

I am on MacOS Sequoia 15.2.

First off you need to use a multi output with BlackHole as the default output. And don’t use an aggregate. It doesn’t mix audio together.

Still grey. Hope I followed the steps correctly.

Removed all previous custom devices

Multi-Output Device with Primary Device as Blackhole. First Audio device is Macbook Pro Speakers, as per wiki.

And don’t use an aggregate. It doesn’t mix audio together. (I don't know what this means)

Next, I created an Aggregate Device. Macbook Pro Microphone first & then Blackhole, as per wiki

Note: Everything was working well a month ago, and I already tried reinstalling. It's still grey, thanks for the reply though, appreciate it!

What do you mean by "still grey". I see absolutely nothing wrong in your photo.
