I have the same error and found this.
Core Audio - Known Issues

To improve security and stability, using launchctl kickstart -k is no longer permitted for critical system processes. If a process must be forcefully terminated, it is recommended to use kill instead. (123028502)

Solution: With OS X Sonoma 14.4 update there is no rights to relaunch coreaudiod - https://forums.developer.apple.com/forums/thread/748228?answerId=784882022#784882022

sudo killall coreaudiod

[krehel]

Yes, I patched the Cask files for blackhole-[2|16|64]ch to account for this after it was raised to our attention last month.

We had a discussion the other day about the solution, and someone was kind enough to write a small patch script - https://github.com/orgs/Homebrew/discussions/5291

[emindeniz99]

Thank you @klaushardt and @krehel, I solved my problem with removing the uninstall cask script from local file and kill coreaudiod manually.

I didn't search the issue in discussions, sorry for my mistake.

Manual editing is required for all users. Is it correct because there is not any method to update installed cask in local homebrew metadata?

[bevanjkay]

@emindeniz99 No there isn't, because the uninstall process can often change over time, so we use the version that matches the currently installed version. If you were to remove the cask's directory from the Caskroom, and use brew reinstall the latest uninstall script would be used instead.

I uninstalled the old version by manually modified /opt/homebrew/Caskroom/blackhole-2ch/.metadata/0.5.0/20231116152617.059/Casks/blackhole-2ch.rb at line 18-23 from

    system_command "/bin/launchctl",
                   args:         [
                     "kickstart",
                     "-kp",
                     "system/com.apple.audio.coreaudiod",
                   ],

Thx @kyan001!

I had to modify it as the new recipe states (commit):

    system_command "/usr/bin/killall",
                   args:         ["coreaudiod"],
                   sudo:         true,
                   must_succeed: true

A potentially easier solution is to remove the file from the Caskroom and then reinstall it.
This will cause Brew to use the most up-to-date uninstall stanza, instead of the one that was present when the installed version was installed.

Silicon Mac
rm -rfi /opt/homebrew/Caskroom/blackhole-2ch/

Intel Mac
rm -rfi /usr/local/Caskroom/blackhole-2ch/

Then reinstall
brew reinstall blackhole-2ch

BlackHole was transfered during the migration from my Intel Mac to the Silicon Mac. It worked after these commands:

rm -rf /usr/local/Caskroom/blackhole-2ch/
Then install again
brew install blackhole-2ch

bakcground-music had exactly the same issue, this file can be modified to fix it.

sudo nano /opt/homebrew/Caskroom/background-music/.metadata/0.4.0/20231225152717.155/Casks/background-music.rb

A potentially easier solution is to remove the file from the Caskroom and then reinstall it. This will cause Brew to use the most up-to-date uninstall stanza, instead of the one that was present when the installed version was installed.

Silicon Mac rm -rfi /opt/homebrew/Caskroom/blackhole-2ch/

Intel Mac rm -rfi /usr/local/Caskroom/blackhole-2ch/

Then reinstall brew reinstall blackhole-2ch

The worked for me if you dont include the "i" in rfi i.e.: rm -rf /opt/homebrew/Caskroom/blackhole-2ch/

Thanks all!
