After updating my GarageBand to 6.0.5 and OS X to 10.8.5 this morning I am experiencing random cracks and pops when playing back audio tracks in GarageBand.

 

Example

As an example I have used Magic GarageBand to create a project with a single audio track and playing this over the internal speakers of my iMac produces the random cracking and popping. It is not an audio interface issue (running through audio interface does the same as the internal speakers). Doing the same on my MacBook Pro running GarageBand 6.0.2 and OS X 10.7.5 does not give the issue. Before the update the iMac played the same projects without the noises.

 

My iMac is brand new (delivered two days ago) and I added a Focusrite Scarlett 2i2 audio interface today, however this is now unplugged in order to try and isolate the problem.

 

Is anyone else experiencing this issues? Is there a way to roll back to the previous version of GarageBand?

    I have exactly the same problem. My iMac was delivered on 30 october, and after installing everything I started using Logic Pro X, and immediately got dropouts, pops and cracks about once a second or so. (iMac: core i7 3.5, 1TB fusion drive, 8GB). Same problem with Garageband 6.05 and Logic Pro. The iMac came with 10.8.5 installed, and I did not upgrade yet. I am not using any external audio devices, just the iMac built-in speakers.

     

    I have an external disk with a clone of my MacBook Pro (10.8.5)  and a second clone upgraded to 10.9 (I like to try things before I upgrade). I started the iMac from the 10.8.5 clone, and no problems. Then I made a second user account on the iMac (on its own drive), tried Garageband, and no problem.

     

    So I inspected my own account and found a Camel Audio plugin that Logic Pro X had already complained about, and removed it. Problem solved, I thought. Everything was sounding fine.

     

    This morning I started up iMac and immediately the problem was there again. Now I could also reproduce it on the second user account and on the 10.8.5 clone. A bit less severe, but if you play a note for a few seconds, there will be a pop. Sometimes it get slightly better after a while. But the problem persists even if I unplug all USB devices

     

    So I tried my next experiment, the 10.9.0 MacBook Pro clone. Amazingly, the problems are now completely gone. It is too early to declare victory, I already thought it was solved yesterday. I am going to test it for a number of hours, and then upgrade the iMac to Mavericks. If the problem comes back, the computer goes back to Apple and I want my money back.

     

    I will keep you informed.

    I use Carbon Copy Cloner, but if you clone is bootable it should show up under System Preferences / Startup disk, if the disk is plugged in. Just select it and restart. There is also a key combination you can use when booting, but

    I forgot which one.

     

    Not all clones are bootable, though.

     

    I just restarted my mac from the 10.9.0 clone, and still no problem...

    I logged in to my iMac again (internal disk, still 10.8.5) and the problem persists there.

    I made an audio recording with my iPhone, so that you can check that we are talking

    about the same thing. You can listen to it at www.nikhef.nl/~t58/AudioBug.m4a.

     

    Please let me know if that sounds similar

    10.9 installed, and problems gone... for now at least.

     

    I thought they were gone yesterday, but they came back in the morning, so I still have to be completely convinced. Also, I think I did hear two pops in a six minute piece, but it might have been a system sound in the background.

    Unfortunately the pops are not completely gone, but they occur only about once a minute, and are less strong. I mainly notice them occasionally during editing. I haven't hear one in the exported file yet. For me it is not a major problem anymore.

    Just an update: the problem did not disappear completely with Mavericks, but after a week of trying it out I decided I can live with it. I hear an occasional pop, about once every few minutes or so. If I were to use my iMac for live performances this would be totally unacceptable, but during editing its is not disastrous.

     

    I tried my two external clone partitions (a slow Samsung disk) again. With 10.8.5 there were a few pops, with 10.9 I could not detect any. This means that this external disk functions better than my internal fusion drive.  With the 10.8.5 configuration delivered to me by Apple, with a fresh logic install I heard this: www.nikhef.nl/~t58/AudioBug.m4a

     

    Is the fusion drive to blame? Hard to believe, but what else explains the difference between 10.8.5 on an external and the internal disk?

    Finally, the problem is solved. I noticed a line

    • Fixes an issue that may cause audio distortion on certain Macs

    in the Mavericks 10.9.2 release notes. I am still not sure if this refers to the problem discussed in this thread, but the fact is that it is gone. I have used Logic Pro under 10.9.2 extensively this weekend, for the first time without any cracks and pops.

     

    Under 10.9.1 the problem was still annoying enough that I was considering bringing my brand new iMac to an Apple Store. Fortunately, that won't be necessary anymore. If anyone reads this who helped fixing it, thanks a lot!
