    I downgraded to Lion and posted that it fixed the problem. I was wrong.


    To review the history here; I was SL, jumped to ML, hosed audio, rolled back to Lion which I was running on my non-studio computer. However my late 2009 iMac is still experiencing pops clicks since leaving SL. I run a locked down tight system, audio always works, and I never update more than one thing at a time so I can pinpoint problems. So it's 100% Lion/ML.


    Tried the usually stuff, reinstalled Metric Halo audio interface drivers, etc. I don't understand what the deal is here. Now I'm going to have to do a clean install AGAIN on both machines all they way back to SL (none of my devices will be synced then but at least audio will work).


    Really annoying.

    I feel your pain.  Apple is working at the speed of molasses on this issue it seems.  If you have a time machine backup of when you last knew your system to be stable, do the command R trick at boot and then restore to that time capsuls backup date.  That should fix it for you.

    Thanks a lot for your constructive comment, i.campbell


    I collected some data while playing music and video in different applications, I hope it might be useful for Apple to resolve the issue.


    The current situation for me is as follows:

    My system is less impacted now than it was initially when upgrading to ML. Applying ML patches, cleaning caches and following most of the other proposed means to repair the system helped a bit, but it's by far not resolved. The error is now happening after some initial fullscreen graphic activity, then sound stuttering can be observed, and usually it gets better after a few seconds, and happens again in a certain time (minute) interval, somewhat regular, somewhat repeatedly, seemingly related to graphics changes and hence CPU/GPU or disk activity. I had two full system crashes when my iMac suddenly rebooted when recording the latency data below The crash reports were submitted to Apple linking to this discussion, but I did not receive any feedback.


    The following log file was collected when playing music with mplayer, iTunes and especially Videos in Plex. So the file contains multiple runs. For the last run (end of the file), the following values were reported:

    • maximum latency(usecs)   17014          21959
    • exceeded threshold           6            645

    Kind Regards

    I spoke w Metric Halo (makers of the best audio interface in the world). These guys are always on the ball...


    They are aware of the bug, they have already reproduced it in their lab, they are attempting to reach out to Apple, and even though the bug is in ML they are attempting to find a work around on their end. In the mean time ML is unreliable for recording.


    For future individuals who google this a few key words to help the search find this thread:  mountain lion unreliable for recording, issues with sound on mountain lion, audio bug, mountain lion not usable for pro audio, etc.


    Trying to warn innocents from stumbling into this trap. Apple built its business on the backs of creative types. Now it's for soccer moms who twitter all day.

    Interesting how 3rd parties are now getting involved.  You know it's getting bad when they are contacting apple about Mountain Goat.  And it's been out 3 months now?!?!  I don't understand how it can be reproduced this easily and they are having a hard time identifying it.  Seems odd.  Or they have seen it, but are clueless as to how to fix it.

    My sound works now, but everything else doesn't.


    This is really beyond frustrating. Updated to ML, sound sucked, downgraded to Lion, but problems, did cmnd R or whatever to reinstall Lion from Apples server, but all my apps are hosed. This Lion instal does not update apps, I have a bunch of ML apps still installed on Lion!  Of course they won't work. Mail, iPhoto, nothing works. I don't have a lion apps disk because my MacBook Pro came with a SL disc (nobody gets a Lion disc).  I can't even revert back to SL because the computer gets a panic attack and says the disc it came with is not the right disc!!!


    What the heck apple? I own $10k USD in Apple hardware and half my junk doesnt work right now.  I've tried support and it just goes in an infinite loop with nobody doing anything except telling me what I already know.  A guy named Chris contacted me, and then disappeared without a word. They sent me an email asking me to rate me call w Chris. There was no call!!!


    Is anyone home at Apple???  WTH.

  • BarrettF77 Level 1 (45 points)

    Curious if Apple engineering has given anyone an update or had them sign a NDA for trial of new software.  Only ask because they have had me do this in the past for stuff.

  • LouFace Level 1 (0 points)

    I've been having some issues with my net dropping and videos buffering all the time (started before installing ML), so the company asked me to boot up in safe mode and see if the problems persisted.


    Once I did it became apparent that no audio or video would work. Whether it be streaming videos online, watching videos on a media player or listening to music on iTunes, absolutely nothing worked. It also appeared that ads did not work, any ads on web pages flickered erratically.


    Something tells me it's too big a coincidence that I happen to have a sound/video issue in safe mode also.

    Ok guys, I'm going to try and re-install Lion.  As I'm a complete newbie to all this, I'd love a little bit of guidance if that's ok, there have been a few pointers in the thread, but I just want to make sure of what I'm doing.


    As you know from earlier posts, I tried to reinstall Lion simply by downloading it from the App Store.  It did download, but I got an error when it tried to install.


    I still have the 'Install Mac OS X Lion' in my Apps folder, so what should I do next?  I've copied all my important documents over to an external hard drive so I can move them back over 'if' I get Lion working again.


    Do I need to copy the 'Install Mac OS X Lion' across to the external drive too and do this 'Cmd + R' thing and load it from there?!


    I'm such a newbie dork.

  • Pink Mink Level 1 (0 points)

    This is all becoming a complete farce for me.  I found a site telling you how to do the clean install.  First, make a partition on an external hard drive to place the Lion installer.  Well, I'm screwed on point one - I created a partition using Disk Utility and now it's just stuck at 'shrinking the disk'. 


    It's being doing it for ages and the status bar hasn't moved.  A search on Google seems to indicate it should only take a minute or two, if it's taking any longer then I could be looking at this bar for a couple of days to complete...or I force the process to stop and risk losing the data that was on the external hard drive.


    I was p@#sed off before, now I am fuming.

  • BarrettF77 Level 1 (45 points)

    If you have a time machine backup, use it.  Then you can just revert back to the exact way your computer was prior to lion.  But I'm guessing you don't.  The only other option I think you have is going to be to back everything up, shutdown, boot holding command R, and the format and install the operating system.  It sounds like the software is so badly messed up from all the silly things we've had to try and Mac our macs work stuff is just getting even more discombobulated. 


    Believe me when I say I feel your pain.  I couldn't even use my iMac for 3 months under ML.  I did a restore on time capsule using TM and went to my restore on July 19th before this whole thing started.  I'm also buying windows 7 for both my computers once the price comes down a bit more.  My family and friends have lost all faith in them.  Their stock price is also showing this as the honeymoon period is over and we now see how the company is going to operate under Tim Cook. 


    But, hopefully my first paragraph helps you out. 

  • Pink Mink Level 1 (0 points)

    Thanks dude, but you're right, I don't have a back up of the data on the extrnal drive.


    I have two external drives - one serves as my Time Machine backup which had everything on it, but during one of my many Mountain Lion crahses the disk became unreadable as it shutdown as a back up was in progress.  The guys on the WD forums said it's screwed and I'd have to ditch everything and lose my backups to start again as Mountain Lion just couldn't 'see' the drive.


    I decided to shift most of my valuable data over to my second external drive as I knew it was unlikely that Mountain Lion would be staying on my mac for very long and I no longer trusted Time Machine.


    So, to re-install Lion, one of the tips on Google was to create a parition on an external drive.  I assumed this was a straightforward process, it never even crossed my mind that it would just hang there forever!


    I've tried copying data back across from the external to the mac, but I keep getting errors.  I am so p*#sed off.


    I'm going to force disk utility to quit and hope I can repair whatever damage that may cause.

  • BarrettF77 Level 1 (45 points)

    Despite that drive being what you said it was, shut down and connect it, then boot into command R at startup.  Once there, see if it will see the time machine backups that way.  You might be able to have it see the lion backups from there.

    Rob Pike, one of Google's Go creators, recently thanked Apple for such similar "pain in the aѕѕ" personal experience. I just remembered it almost immediately.

    Well, last comment is not being shown as I edited, here it goes again:
