background-music update error unable to kickstart CoreAudiod

[michaelTward]

attempting to upgrade background-music with homebrew failed, due to an inability to kickstart CoreAudio. This permission was revoked in a recent MacOS update.

A solution that worked for me for background-music, based on a solution for a similar problem for blackhole-2ch was 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/background-music/

Intel Mac
rm -rfi /usr/local/Caskroom/background-music/

Then reinstall
brew reinstall background-music
