Focusrite Scarlett 2i2 clapping and crackling issues with Logic Pro x new iMac 27"

Hi, I have just purchased a brand new iMac and downloaded Logic Pro x, I also purchased the Focusrite Scarlett 2i2 interface. I have downloaded the drivers from the focusrite website and everything is set up, when I plug in guitar or mic I get really bad clapping and crackling to the point where the sound cuts out altogether. I have changed buffer size and sample rates and everything else I can think of but nothing seems to fix the problem. I also deleted the 2i2 drivers and logic and reinstalled them both but still have the same issue, when I record using the iMac built in mic everything is fine so it's deffinately something to do with the interface. I am waiting to hear back from Focusrite tech help. Does anyone else have this problem? Any help would be appreciated.

iMac (27-inch, Late 2013), iOS 7.0.2

This worked for me! Hope it helps you!

This is the email I got back from the support and the the solution for me.

"Thanks for your call and sorry to learn of the problems you are having with your Focusrite product.

Some users have reported experiencing audio glitches and drop outs with the Scarlett range of interfaces since updating to OSX 10.9 Mavericks. If you are experiencing these problems with your interface, it is possible to utilise Apple’s USB audio driver by downloading and running the class compliant mode application below, while we investigate further.

Please note: After the class compliant mode application has been unzipped, please right click on the application and choose "Open". If you do not do this you may get an error message from the Apple Gatekeeper service

Are you saying the Gain knobs on the front of the unit have no effect on recording level?

I have the same problem. The Focusrite Scarlett 2i2 worked just fine with my MBP 17". When I got my new Haswell iMac 27" (with the i7 processor, 24GB RAM and 1TB Fusion Drive) the soundcard started to crackle. It works just fine with the internal soundcard. The software is exactly the same on both machines.

It's really frustrating, I have changed every setting I can find but it doesn't make much difference, I am still waiting to hear back from the focusrite tech guys and I will update this post on the outcome. I am in Australia so it's not so easy to pick up the phone and call the UK, hopefully I will have some response soon!!

I'm having a similar issue which might indicate that the problem is not your interface.

Yesterday I migrated all my stuff from my 2009 iMac to a brand new iMac 27", and when I did a quick test to play back some old projects in Logic there was loads of annoying clicks and pops. My interface is a Roland Octa-Capture.

I also noticed some weird CPU spikes from time to time, which I never had on my older, much less powerful iMac...

Hi Stevie. I have sorted this out. It now works perfect after speaking to focusrite

You have to goto finder, then Macintosh HD, then system then library then goto the file focusrite USB file and drag it to the trash. Re start the mac and all should be perfect.

No.. (Well, not after a certain period of time..) but I will 'report' the various messages and ask for them to be removed because they contain personal emails and see if one of the forum sysops will delete /edit them for you.....

Oct 9, 2013 11:15 AM in response to The Art Of Sound

I tried the File from Focusrite but it didnt work for me. So I also send them a message about this as well. I hope that they can see that there are more people with the same problem and will fix this soon.

The Art of Sound, thank you! Looks like I may be stuck in two problems here, at worst.

Do you think this bug is reported to Apple yet? Not shure how to report the problem to them...

I have the late 2013 27" iMac with Fusion Drive so I guess your link is spot on my problem

Art of sound,

Thanks for replying. In my case with apple care now they want me to reinstall mavericks completely. I hesitate on that. I think your thesis on this problem is more accurate and a reinstall would not be the solution, only half a day wasted time.

Can you please post a link on how to split the fusiondrive through ext HD menthod as you mention?

I would need a step by step walkthrough or something.

Cheers!

Thanks Art of Noise for replying

Maybe this is a dumb question but if I make a external boot drive with diskmaster x, do I need to move all my content to that drive of will it just be the system there.

Can it in that case be done on a USB thumbdrive of say 32 gb or do i need to install it on a normal external hdd?

Nov 23, 2013 7:22 AM in response to lagstrom

Hey Lagstrom

You have to put everything on the external drive that was on your internal System Drive so the FD isn't needed or used at all.... which is why a thumbdrive usually won't do because of it's limited capacity....

No. When I plug in the 2i2 USB, the recording level control (as well as the automatic level control) in GarageBand becomes inop...as youcan see, they're greyed out..... any help would be greatly appreciated...

BTW... great lookin' guitar!

That would be normal for a pro, semi-pro audio interface.

The input level controls are on the front of the 2i2 hardware, "Gain".

That's one of the inexpensive PRS guitars, they don't make that model anymore.
