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

    Just to make a note that the problem with coreaudiod not responding happens regardless of the chassis. With the MacBook Pro running on its own, nothing attached to it, I still get the same errors in Activity Monitor whereas coreaudiod shows as Not Responding.

    I am not sure if these two issue existed before 10.5.3 or not but they do exist now in the Activity Monitor. I have the following 2 issues:

    - coreaudiod (Not Responding)
    - UserAgentEvent (Not Responding)

    I was able to resolve the "UserAgentEvent (Not Responding)" issue by deleting "BluetoothUserAgent.plugin" from "Volume\System\Library\UserEventPlugin"

    I have not yet been able to resolve the "coreaudiod (Not Responding)" issue. Any ideas and suggestion would help.

    I have the same issues with a Macbook and a G4 Dual MDD 1 GHz. Both with Leopard 10.5.3. So it isn't an intel related issue.

    Same problem here exactly. Looking forward to a solution, I can't seem to resolve this on my own.

    Ahh Ha! How many of you are using a new little application called Hear?

    What's new in this version(1.0.2):
    ** Fixed problem where Hear was causing 'UserEventAgent' process to show as 'not responding'.*
    ** Fixed problem where Hear was causing 'coreaudiod' process in 10.5.3 to show as 'not responding'.*
    * Fixed a bug where the EQ settings were not getting enabled unless the Hear application was launched first.
    * Fixed a bug where the EQ Resolution popup was not detecting mouse clicks on the right side of the popup.
    * When running in demo mode, the user now has the option to uninstall.
    * Uninstall now prompts to the user to restart their system, to completely uninstall everything.
    * Added '96' as a new default choice in the EQ resolution popup.

    Updating worked for me, yay!

    I finally solved a problem on Apple Discussions, please mark this problem solved so I get a star, whee

    I just installed the update for the app Hear (current version 1.0.2) and that seemed to have resolved the issue for me as well. Thanks for the info and update "Macophile". Peace out.

    I have the same problem with CoreAudiod(Not Responding)
    I is the Digidesign Core audio plug in causing the problem. I'll bet you have ProTools 7.4.2 for Leopard installed right? Well, if you uninstall ProTools ,the problem goes away. You could also delete the Digidesign Core Audio Plug in from the MacIntoshHD>Library>Audio>Plug-Ins>HAL
    But then Core audio will not operate, but ProTools will still operate .
    Hope this helps

    I don't have Hear, and I've tried to uninstall Pro Tools in my system but still, both coreaudiod and UserEventAgent are not responding. So i tried to looking for other possibilities. After searching thru the net, it turned out that if your system has Blackmagic-Design Decklink Drivers installed also caused both functions to stop responding.

    Uinstalling the decklink drivers is the only way. But this will also stop you from using the Decklink card installed.
