10.5.3 coreaudiod (Not Responding)

After installing 10.5.3, the process coreaudiod in Activity Monitor shows as not responding. Quitting the process does not fix it, since after a couple of minutes it goes back to not responding, even when letting the computer idle without opening or closing any applications.

I have tried fixing permissions, zapping the PRAM, threw away coreaudio and audio preference files, but it always comes back. Audio applications seem not to be affected by it with playback and recording working without problems.

However, when I connect a Magma PCI Expansion chassis to the MacBookPro, several problems appear.In the finder, the icons on the menubar for the clock, wireless signal strength, audio
volume, etc. dissappear, only the spotlight icon remains. It is also impossible to turn them on via the control panels in system preferences. Clicking on the radio button works, but then resets itself to not clicked! right in front of my eyes.

Also, the system enters an error loop. In activity monitor, the process SystemUIServer continuously generates crash reports that get written in the Console's log.

It may be that the Magma chassis is not compatible with 10.5.3 although it is recognized in System Profiler, with no errors and claimed to be compatible.

Anyone else seeing this in Activity Monitor?

MacBook Pro 2.6Ghz (Penryn), Mac OS X (10.5.3), 4Gb RAM

Of the various third-party software mentioned in this thread, I only have ProTools LE 7.4.2. I, too, have the same problem with coreaudiod, but I don't want to uninstall PT right yet.

What are the consequences of coreaudiod "not responding"? I haven't noticed any audio problems so far.

Thanks,
Chap

Thanks... this fix worked fine for the UserEventAgent (Not Responding) problem I was having too.

Another bump for this thread!

I have Pro Tools 7.4.2 which I can't uninstall, I don't have Hear or WireTap, so if I don't find anything else online I guess I'll just have to go through all my programs that might use coreaudio and update them, yeh..? rubbish - anyone found any other specific programs that might cause this?

Cheers!

I also had the coreaudiod not responding issue, but do not have Pro Tools or Hear installed. However, I had installed IOXperts camera drivers. after uninstalling (http://www.ioxperts.com/FAQs/faqwebcamx.html#removeanchor), things seem fine again.

I have 10.5.6 and had the exact same problems. I deleted the bluetooth BluetoothUserAgent-Plugin (actually i just moved it from the UserEventsPlugins folder and placed it at the root level of Macintosh HD in case i really need it again) but that did NOT fix the problem of coreaudiod not responding.

I have a BlackMagic Decklink card and had recently updated the drivers 6.8.7. After reading several different forums here and at creative cow, I went back to several previous drivers. None of them solved the problem. It was only after reading this forum that I seemed to be able to fix the problem.

Someone mentioned a file in the HAL folder that ProTools installed. I've never had protools but on a whim I deleted (moved) a similar file associated with the BlackMagic Decklink.

*If you have a BlackMagic Decklink card Go to Macintosh HD>Library>Audio>Plugins>HAL and DELETE (or move) DVCPROHDAudio.plugin and restart your computer. That should fix the problem of coreaudiod not responding. It worked for me.*

Don't know if that was also throwing the previous useragent error too since I kept the bluetooth file out of its intended folder and have run out of patience for troubleshooting.

I had tried everything else in every forum I read on this issue, from deleting countless plugins and library files, to software update, to repairing permissions, to... (well, you get the point.) If you haven't tried this remedy, I highly recommend you give it a shot:

This is a known issue with the latest version of Pro Tools.

It doesn't cause me any obvious problems, but it would be nice if Digidesign released a fix.

Well i have 10.5.6 too, i noticed, i have only SRS iWOW installed, so i uninstalled it, and yes, the problems with coreaudio is gone...

Ya I mean I got this problem with both Coreaudiod and UserEventAgent when I first installed protools 7.4 LE. After I installed 7.4 I discovered that 7.4.2 had become available. After uninstalling 7.4 and upgrading to 7.4.2 my UserEventAgent started working normally. As for the coreaudiod I removed the digi core audio plug in from HAL and coreaudiod is now working normally. Is this a good thing to do. what exactly does it effect?

Had the same "coreaudiod" problem and solved it by removing "WireTap Anywhere" as described above. This was about 10 minutes ago and everything still is fine in "Activity Monitor". Thank you, Chris71124!

It seems to me like some programs (just like HAL, Digidesign, Hear or whatever was mentioned as influencing "coreaudiod" 's behavior) make "coreaudiod" wait for things that don't come, thus making it hang in a loop (not responding).

Good luck to everyone who tries to find the app that's killing "coreaudiod" in their system.

To me, the problem seems to be solved.
