coreaudiod

About 3 days ago i did an update to Mountain Lion. First all went very well but when i started a video my mouse began to jerk. I saw that the process coreaudiod went up to 20 - 30% cpu usage. I read in the communities that i have to Pram reset, Repair the Volume delete audio files, change coreaudiod.plist from false to true and so on. I did a complete reinstallation and later also a downgrade from mountain lion to Lion 10.7.4 but it didn't help. I don't know what i should do?! Can anybody help me? Got an iMac 27" Mid 2011 Core i7 12GB RAM

iMac (27-inch Mid 2011), Mac OS X (10.7.4)

I had the same issue and tried a lot. But in the end, it was this hint: http://www.solidpitch.com/2010/05/11/when-your-mac-doesnt-remember-the-sound-set tings/

...

Deleted the Audio folder located at [OSX HDD Name]/Library/Preferences/ and create a new one as root in the terminal:
"sudo mkdir /Library/Preferences/Audio"

then set permissions:
"sudo chown -R _coreaudiod:admin /Library/Preferences/Audio"

Cheers, Roland

Dear Everyone,

I tried all the above procedures but my issue didnt resolve. Then after 3 days I downloaded Mac Mountain Lion X and reisntalled it and my problem is solved now 🙂

If all the above mentioned procedures doesnt work for you then you should reinstall your operation system.

Thank you everyone for sharing your experiences.

For those mystified by why this fix seems to work for everyone but them and, at least in my case, coreaudiod was only using 6-8% CPU rather than 100%+ like the others here, my solution turned out to be to close my Google Play (Google Music) tab in my browser (Chrome). It appears Google Play/Music on Chrome makes coreaudiod use 6-8% CPU even when no music is playing or has even be played yet. Hope this helps someone else! (for completeness: four-day-old 13" MacBook Pro 2.6 GHz i5, fully updated, 10.8.5, Google Chrome 29.0.1547.76)

Awesome trick!

I've got a SnowLeopard VM running on an Ubuntu 12.04 LTS VirtualBox host I use remotely to manage mail, BusyCal, and run Photoshop since my Lion mbp and Mavericks Mini can't run it, any more..

No sound ever comes out of this thing, since I only connect to it through an ssh-tunneled vnc session.

The coreaudiod process only takes up 5-10% CPU at any given time on this VM, but still... Waddaya gonna hear from a virtual machine? It's not like RD, right...

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

CPU down to nil...

Danke, man!

I was having this same issue. My coreaudiod was running up to 315%.

Eventually I found this page:

http://apple.stackexchange.com/questions/24913/why-is-the-coreaudiod-daemon-usin g-5-or-more-cpu

Which basically means that you download Onyx, run the cleanups and make sure all the audio stuff is checked, then after it restarts, repair your startup disk's disk permissions with the Disk Utility. I figured out that my problem was exploding every time I plugged speakers in.
