    Steve Jobs, we need you! Help us!

    I am totally frustrated because of this annoying sound.

    Is there any possibility to switch back to Lion if I don't have a Lion Install Disc?

    I am also badly bitten by the stutter bug. I took arecording of it to send to Apple care sometime. In the mean time I was streaming using nicecast into Secondlife and listening to my music is Secondlife. The sound started its stuttering. Leaving the mac alone, I connected to my stream on my iPhone and the music I was streaming was perfect. I then played the music over airplay to a local loudespeaker from the iPhone. The stuttering was still on the mac however.


    From this I can only conclude the problem lies in the way OS X is deliverng the sound after decoding to the audio system. Nice cast captures the music after the pogram, iTunes, Djay whatever, has decoded the media info but before it gets delivered to the audio device.


    I think


    I get the stuttering on the interal loudspeakers, a USB sound card/headphone and built in headphones.

    have you tried 10.8.1?



    I've still been without an audio problem since updating. Normally the audio bug would hit be once daily.

  • Victor In Munich Level 1 (135 points)

    No, I have no access to 10.8.1

  • Victor In Munich Level 1 (135 points)

    Looks like I was to optimistic here. After about 2 hours, I got the breakup on the outgoing stream.

    Anyone having access to 10.8.1? Please tell us if the bug is fixed!

    I am a registered devloper with apple. I have access and have installed 10.8.1 on a Imac 27 inch mid 2011 with 12 gig of ram.


    Sadly it still stutters with Video, Games and also itunes. The system is faster that is noticable but sadly the stutter glitch remains.

    Found a fix after spending an entire evening trying to fix this... (I'm on a retina macbook pro, so I'm not sure if this option is on other macs)


    Go to System Preferences

    Energy Saver

    Uncheck 'Automatic Graphics Switching'


    No more sound stuttering/crackling.


    I'm guessing the issue lies in the integrated video card.  When using the Nvidia (by unchecking the above), the problem completely disappears.  However, still isn't acceptable as a fix to me as my battery life worsens as I'm always running off the Nvidia card in OSX.  Btw, this sound/stutter issue is completely nonexistant in Bootcamp.  So it 100% is a software related bug in Mountain Lion.

    Looks like we got the issue isolated somewhat.


    I'm on a 13" Macbook Pro and so only have an intergrated video card.


    Maybe it's a video card driver problem. Let hope Apple can fix this soon.

    Well, I'm on a 13" early 2011 macbook pro with integrated intel 3000 hd graphics and suffer stuttering anyway.

  • rxghost12 Level 1 (0 points)

    yea def looks like it's an issue with the integrated graphics driver. 


    Anyone who has a retina display or who has the ability to switch between two graphics cards (between integrated and nvidia) on their macbook, etc.  Please test out just the nvidia alone.  I'm sure that will cure the crackling, stutter effect for the audio.  I'm guessing there's some bug with the integrated graphics driver within mountain lion causing the audio issues.

    I'm glad that this solves the problem for you, but it is not the total answer.


    Many of us have iMacs. We don't have that option in the Sys Prefs.


    The stuttering happens with video and/or audio.


    Let's hope Apple finds the problem, but from other posts, it looks like 10.8.1 will not correct this issue (at least for everyone).



  • rxghost12 Level 1 (0 points)

    regardless of whether you have an imac or macbook pro/air.  The issue does in fact lie with interaction of the integrated graphics with mountain lion. 

  • Lvivske Level 1 (0 points)

    imac's dont have integrated graphics so that kills that theory

  • rxghost12 Level 1 (0 points)

    Anyone try out the new 10.8.1 patch?? So far I'm not getting any popping/crackling/buzzing... but it does come in randomly so we'll see... hopefully this fixed the issue..
