Coreaudiod not responding

Hello All,
I happenned to look at my activity monitor, coreaudiod (owned by root) was in red. I remember this happenning a couple of times earlier (last 6 months?). When I restart my computer it is OK again, but probably goes red some time again. Do I need to worry too much? Any trouble shooting I can do? What I have done recently is to delete imovie and iphoto (the version that came free with 10.2) to free some space. Any help is very much appreciated. Thanks in advance.

That is almost certainly not a glitch with coreaudiod, but with Activity Monitor not refreshing its info correctly. (If anything were really wrong with coreaudiod it would be re-launched by launchd. Force Quit it in Activity Monitor and watch what happens!). Whenever you see coreaudiod in red just quit Activity Monitor and immediately re-launch it. In black now, eh?
BTW, the glitch with Activity Monitor is not something for you to try to cure – it's down to Apple.

I am not sure if this will help, but hidden away is an audio forum that deals directly with coreaudio.
It might get you a bit more assistance.

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?

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
Great!! Solved on both computers!! Thank you!!

Coreaudiod root process- not responding?

I installed a new graphic card ATI 23870.
The card's fan runs all the time so;
I switched on Activity monitor and selected all processes.
I noticed Process ID 145 coreaudiod (Not Responding) in red.
I went to force quit and was told it was a root process.
What is this?
What would cause it not to respond.

Perhaps some hints in this thread:

Coreaudiod and UserEventAgent both not responding

I noticed in Activity Monitor showing all process on a clean boot I get both coreaudiod and UserEventAgent both not responding. I though this might be something to do with sound but the funny thing is everything seems ok. Audio and video and the general running of the computer seems to be fine unless i had not looked in activity monitor i probably would not of noticed.
If i quit both processes they dont appear again in red not responding.
But if i start an app or play a sound ot video they both pop back up again as not responding yet the system functions as normal seemingly and sound and audio works fine.
Any Ideas. Sure seems a little strange.

OK fixed it after a bunch of research I found 2 plugins that can ause problems in the
go to :
Library\Audio\Plug-Ins folder
I had a folder called HAL which had a plugin for protools which i dont have anyways and i deleted it. Also there is a app called Hear which had a plugin i deleted as well. So basically if you are having similar issues check the various plug-ins in these folders and try removing them The Protools one is a known culprit as well as the Hear one.

CoreAudiod keeps showing not responding

Everything here good after upgrading to 10.5. However I have noticed in my processes that COREAUDIOD keeps showing up not responding. I can kill it and then it will restart but goes unresponsive again after awhile.
Any one else seeing this? Any thing to look for?

Yep,
I have exactly the same thing, and there's no fix for it.
Some people have mentioned deleting everything to do with DigiDesign (an audio plug-in), but I don't even HAVE those in the first place, yet coreaudiod decides to hang.
Very frustrating.

1) Compressor artifacts and 2) Processes not responding

The whole reason I switched from Windows/Premier to Mac/Final Cut was to avoid broken software. I'm beginning to think the Mac is no better. Well, that's not entirely true. I think OS X is more stable than any version of windows but DVD Studio Pro 4.0.2 is a step back in stability at least for me. Before upgrading to Tiger and FCS, I could reliably build and burn DVDs. Now I can no longer pry a complete working DVD out of DVDSP4.
I've got so many problems and so many questions I don't know if I should post them all in one message. I guess I'll keep them in one message but try to keep it short.

BACKGROUND
I shoot and edit a weekly local soap opera: http://www.shadesoflife.net
Each time I complete four episodes I create a DVD with these four episodes on it for the cast. This DVD I'm working on is for episodes 92 through 95 and I'm adding chapter marks and scene indexes to the DVD. By using the DVDSP templates and the correct drop zones, this has been quite easy, except for the fact that I can't seem to get the video to import any more.
Actually I got three of my four episodes to import just fine. These were exported from FCP as stand-alone QT movies and included chapter marks. Episode 94 would never finish the background compression step when importing into the DVDSP project as an asset.
Because of the suggestions I read in other articles in this discussion group about this kind of problem, I deleted the episode 94 audio and video assets from the project along with all menus which referenced them. I then started Compressor and transcoded the Episode 94 stand-alone QT movie and got these two files as a result:
"SOL-094-DVD PCM Audio-.aiff"
"SOL-094-MPEG-2 60 min Fast Encode-.m2v"
Next I imported these assets into the DVDSP project and used them to build the menus. This went smoothly. But, when I run the DVD simulation in DVDSP, episode 94 shows serious artifacts which render it unwatchable.
QUESTIONS: What Compressor encoding settings should I be using? What is the meaning of "60 min" and "120 min" in the encode settings? If I use a "120 min" setting will the file be bigger or smaller?
As I set here after reading the similar problems people have posted and the solutions and work-arounds people have suggested I see that a number of processes are not responding, according to the activity monitor. Generally this means that something is broken, but what. After rebooting OS X, running Compressor and then DVDSP I see the following processes that are not responding:
- compressor
- coreaudiod
- DSPX_AEncoderServer
- DSPX_EncoderServer
- two copies of MediaServer
When I exit DVDSP all but the top two disappear. What is "not responding" a symptom of?
I could sure use some help here. Thanks.
Peace,
Rob:-]

Same here :
It seems this problem started after updating QuickTime Player 7.0.2
when I open the Simulator in DVD 3.0.2 I can see (in Activity Monitor) 2 processes coming up : DSPX_AEncoderServer and DSPX_Encoder.
Instantly they turn red and get (Hung) added.
The 'inspect/open files' for DSPX_AEncoderServer:

/System/Library/Frameworks/QuickTime.framework/Versions/A/Resources/English.lpro j/Localized.rsrc
So, in both files it stops with QuickTime.
We have QuickTime Player 7.0.2
So, if you read this, can you please help !!!

2 processes not responding

I wanted to check how ram I had available for a certain task (I had plenty extra) and opened Activity Monitor. I noticed in passing that 2 processes were in red and were "Not Responding". There are UserEventAgent & coreaudiod. They are using .5 & .6% of cpu you power constantly, which is a little concerning.
I have noticed this several times recently. I tried to quit process but they won't stop. I realize it's not really hurting anything but it would be nice to stop them. Thanks.

You probably have an audio enhancer installed such as OSS 3D or SRS iWOW or a version of Hear prior to 1.02. You will need to uninstall it completely. Only Hear 1.02 will work properly.
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Most applications create preference files which are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can located them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term.
There are also several shareware utilities that can uninstall applications:
AppZapper
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning
Look for them at VersionTracker or MacUpdate.

I can't open firefox the running but not responding window opens and says to close the existing window. I can't do that shutting down the computer doesn't do anything to help. I've done all the suggestions here. I've uninstalled and reinstalled firefox

Firefox will not open. I get the firefox is already running but not responding window... I have tried rebooting with no help. I have tried to end the process via cntrl+shift+esc and nothing firefox is listed to end. I have tried find the app data via the run icon in the start up window, I have no run icon on this system (Acer with windows vista(?)
== This happened ==
Every time Firefox opened
== The computer was hard shut down and did a improper shut down scan when it was restarted ==
== User Agent ==

I am having a similar problem. Running Xp.
Latest revision of firefox.
After using firefox for a while if I exit, parent.lock is locked and i have to reboot to reload firefox.
I have killed all firefox applications from task manager (usually there are none). and I have tried 3 different "file unlock" programs including unlocker to no avail.
I also recently installed a program that shows -all- open files, and parent.lock is not listed, and thus not closable/unlockable from there.

Frequently when I open Firefox it says Firefox is already running but is not responding. I have to go to the task manager, find Firefox and close the process before I can get firefox to load.

Those are all the details I have

There is an article about this problem see:

PCI DIO 32HS (6533) Suddenly giving "The device is not responding to the first IRQ level" error, and no longer functioning.

Greetings NI folks,
I'm an oceanographer, and have an sidescan sonar data aquasition computer running Windows XP SP2, and NiDAQ 7.0 (Legacy). For several years, this machine has worked flawlessly, but today, I booted it up to test the system for an upcoming job, and I got some strange errors in our sonar program. I tranced the problem to our NI-6533 PCI-DIO-32HS card. I launched NI Automation Explorer to test that the card was responsive, and when I click the "test panel", I get an error: "The device is not responding to the first IRQ level." Continue (yes/no). If I click yes, I can test the digital i/o's, but nothing happens, and all the tests fail (nonresponsive). I tried moving the card to another PCI slot, tried forcing it to have a specific IRQ that was unused by anything else, and finally tried moving it to another computer that had never been used with the DIO card. I'm still getting the error, and the card is nonresponsive. I'm at the limit of my abilities, and would like to know if there's anything else I can do, or should we send the card back to NI for repair/diagnosis.
Thanks.

I just updated itunes to 11.1.3 on my laptop and now it won't open. It does not respond to trying "safe mode" either. Anyone have an idea as to what to do?

I just uninstalled it and am waiting for it to reinstall. I sincerely hope that I have not lost everything that I worked on so hard. Now that mobile me is gone, I have not been able to go between devices to transfer things. I was merely trying to take a document I had worked on and open it in pages, but it said my version was too old. When I updated, it wouldn't load. Now I cannot do anything. I hope that the reinstall fixes it without losing everything. Please advise!!! Yes, I am in panic mode.

"Update server not responding" when trying to update Acrobat 9 Pro

I just installed Acrobat 9 Pro on my desktop computer and on my laptop. I was able to download and install the latest updates to the copy on my desktop computer (so that it is now version 9.3.0), using Help>Check for Updates.
When I try the same command on my laptop, I get and error message that states "The update server is not responding, which means it may be offline at the moment, or the Internet or firlewall settings may be incorrect. Please try again later." I tried several times yesterday and today with the same error. The message pops up immediatley; it doesn't even seem to actually try to connect.
I disabled my firewall and antivirus software and still get the same result. I uninstalled then reinstalled Acrobat and still get the same result.
I looked online at Adobe.com to see about downloading and installing the updates manually, but it's difficult for me to tell which updates I need. Some are for other languages and some are for 64-bit but I have Windows 7 32-bit.
A call to tech support was no help. The agent seemed to think because I installed verison 9.0 that I only needed the one English update listed on the download page under 9.0, and not any of the later updates. . . And he said that Adobe recommends manually installing updates from Adobe.com rather than using the Check for Updates command (?!).
Anyway, does anyone know what might be causing this problem with the adobe updater? Maybe I need to reinstall the updater (where do I find it?).
OR
Can someone tell me which of the updates listed on the Acrobat dowload page I should manually install to bring my product up to date?
[Running Windows 7 32-bit on both machines]
Thanks.

Hi,
Which version of Acrobat do you have ?
(Launch Acrobat and Go to Acrobat->About Adobe Acrobat menu item and check the version )
Also, can you ping following urls ?
armmf.adobe.com
armdl.adobe.com
ardownload.adobe.com
Are these urls reachable ?
Also, you can check the contents of host file /etc/defaults/host to see that none of the ips are redirected.
One more thing that you could try:
If you have firewall on, could you please disable the firewall and then try the update. Does it works now ?

Adobe Reader 11 w/Windows 7 not responding

Why does Adobe Reader 11 fail to respond sometimes? Re-installing allows it to function several times then we get a "not responding" message. A plank screen is displayed and the number of pages but NO text! Using repair produces the same results. Upon 1st use of the repaired/reinstalled reader 11 we also get the adobe message "Cannot find or create the font "Times New Roman". Some characters may ot display or print correctly". The text is mostly displayed at this point. The second attempt to display the same PDF or another displays completely w/out any error message at all. At some point during the testing process Adobe Reader 11 stops working! Restarts don't help. Shutdowns don't help. Seems only a re-install or repair allows us to correctly view our PDF document a number of times before we have to repeat the process. Is help available?

Moved the discussion from Adobe Reader Touch for Windows 8 to Adobe Reader.
