SoundSource freezing

I can't use macOS anymore without SoundSource. However, it frequently freezes, hangs, crashes, etc. This requires a not-too-lengthy but still annoying manual flow of opening up Activity Monitor to force kill it, then opening it again. So I made it easier and automated.

Shell Alias

First, I always have a terminal open, so I added an alias to ~/.zshrc to reboot SoundSource:

alias restart-sound="killall -9 SoundSource && sleep 5 && open -a SoundSource"

The sleep could probably be shorter, but I found at least some delay is needed between killing SoundSource and starting it again.

Cron job

Then I added a cronjob to automatically restart SoundSource each day (with crontab -e), which seems to be helping:

0 2 * * * killall -9 SoundSource && sleep 5 && open -a SoundSource && echo "restarted $(date)"

Note: I had to add export VISUAL=nano to my ~/.zshrc so crontab -e didn't use VIM since I'm not a VIM user.
