The original solution didn't do almost anything for me - the CPU usage dropped slightly for a few hours then it got back to 5%.
AUDIOSWITCHER FOR MAC UPDATE
Maybe a restart could help but I lately did it for the recent macOS update and didn't do anything, so I doubt it. Stopped every single app that has access to the microphone as people suggested in other forums like StackOverflow - zero effect. However, now, with music or not, `coreaudiod` is firmly stuck at 5% CPU no matter what I do. Unplug the headphones - that are using a normal 3.5mm jack and _not_ USB - and re-plug them. There's some audio driver from immersedVR that came across from my time machine backup that I'd like to be rid of given I haven't had the app installed for 18 months.Īctually mine's back at 5% CPU at all times when idle, and 15% when playing music (iMac Pro so Intel CPU).
AUDIOSWITCHER FOR MAC INSTALL
I am tempted to do a clean install at some point. either they're copied and the dates came across or they're hard links or something? What's also weird is the dates on those files.

What's weird is that if the Audio folder is not owned by _coreaudiod, I go back to seeing 12% CPU consumption permanently, yet all the files that populated the folder are owned by my user account. It had been reliably happening for the past couple of months at least that I noticed. This isn't something that was happening for one reboot.
AUDIOSWITCHER FOR MAC DRIVERS

You should now notice coreaudiod is not constantly high up in activity monitor! In fact, if not playing/recording audio it shouldn't even be running!

Essentially once it starts the daemon, it constantly uses 12-15% CPU. If you've ported your user profile from Mac to Mac over several years, as I have, you may have noticed coreaudiod using a heap of CPU when not playing audio.
