Had to use this after installing Microsoft Teams. I couldn't change the volume anymore.

Sadly no longer working on Sonoma 14.4:

Could not kickstart service "com.apple.audio.coreaudiod": 1: Operation not permitted

update 4/24/24: Apple says "Nope, that's the way we want it." 👎

Following. I'm seeing the same as @luckman212. I'm stuck trying to uninstall blackhole-2ch.

@luckman212 , @crunk1
There is a reference in the macOS Release Notes about this, seems like it is no longer possible to kickstart coreaudiod.

https://developer.apple.com/documentation/macos-release-notes/macos-14_4-release-notes#Core-Audio

If you are unable to uninstall blackhole-2ch because the uninstall_postflight fails you could try changing the postflight command in the following file <homebrew prefix>/Caskroom/blackhole-2ch/.metadata/<version>/<timestamp>/Casks/blackhole-2ch.rb to use a different command or no command at all. Since version 0.6.0 the new behavior is reflected in blackhole-2ch homebrew package.
