Little workaround:

To disable the "coreaudiod"

sudo launchctl unload /system/library/launchdaemons/com.apple.audio.coreaudiod.plist

To enable the "coreaudiod"

sudo launchctl load /system/library/launchdaemons/com.apple.audio.coreaudiod.plist


If you disable you cann't play audio files.


I found some clues at the console that

  • "_AirPlay (Service)"
  • "_raop (Service)"
  • "bluetoothaudiod"
  • "AirPlayUIAgent/AirPlayAVSys"

are creating this cpu overhead.

I did a clean install from my usb with OS X Mavericks, because my macbook was heating up too much and I had to work.


But I found out that the Harddrive and my user account was broken. So I had to delete my ssd drive. After that I was able to reinstall Mavericks.

I will try the same step with Yosemite.


I downloaded Mavericks via AppStore and created a bootable usb drive with Mavericks on it.

This is also possible with Yosemite. And I recommend to do a clean install via usb.

I will give you my feedback next weekend.

Hello,


exactly same problem here on my macbook pro with retina / hd4000. And like Poldy001 suggest, Launchcontrol tool did the job. In my particular case there was bluethooth module blued to unload and load. This solves the whole issue. I ve got some problems with bluethooth when my magic mouse just froze one time and never go back, turning off bluetooth doesnt work. Unloading blued fix mouse, it is working again, and also coreaudiod stops eating processor. In my case in idle mode, before fix, coreaudiod eats 80 % all the time and launchd 40% all the time no matter what was turned on. Now i have again 97% idle procesor status.

Thank you!! That solved the issue for me. I had disabled the blued service on Maverick as I had no use for it... that will teach me for for messing about with services. To be specific, to fix the problem I ran:


$ sudo launchctl load -w /system/library/launchdaemons/com.apple.blued.plist


I guess with OSX we will never know what the actual bug is that causes coreaudiod to hang when it cannot find blued. But at least now I can enable sound again 🙂
