Massive problem with audio interface

Hi there.


I recently bought a brandnew iMac 27" Haswell i7. I encountered problems with my Focusrite Scarlett 18i8 audio interface. These are buzzing, clicking and noise immediately or after 3 minutes or so. I tried everything, re-installed the driveres several times, nothing, really nothing worked.


Then I bought an RME Babyface audio interface - and guess what? It's the same problem. I also have a massive sound noise after some minutes or the recording channel in Garage Band drops completely.


What is wrong here? I already tried using a different power plug, tried all USB ports, turned off WiFi, HDD sleep mode, etc. Nothing worked.


Do you have an idea?


I appeciate your help,

Adrian.

iMac (27-inch, Late 2013), OS X Mavericks (10.9)

Wow apple really dropped the ball on the audio part of there update.


Been having major clicks and pops sinds January!!!! I geuss their main focus is on the graphicworld right now as their are no movements what so ever to get this problem cleared.


I have seen my workflow dicrease to almost not want to work on my imac any more. I love apple,truly do but this is really frustrating.


Just to tip you guys out there who plan to by a different soundcard. Dont border. The cracks and pops also emerge when in this case my apogee duet firmwire is not connected.


What helps is to restart your mac everytime the 8bit sound or clicks and pops appear. which for me is around every 30 min. Such a shame that this is happening. I cant just go and buy a PC all my stuff and plug ins i use are Apple oriented. So basically i'm screwed untill Apple desides to finally adress this manner properly and not with bandaid solutions.


Come on guys. Step up to the plate and let us all enjoy the strenght of Apple computers in it's full form. Im in the final stages of mixing my album and this is just throwing me miles away from my deadline! DO SOMETHING!!

I have the same setup, except I have the Motu 828 mk2 with firewire to thunderbolt adapter. I still get the crackles in Ableton Live.. Also for some weird reason, at a very basic project, with not many plugins in use, my cpu monitor is just as hight as my previous ****** 13 inch i5 macbook pro. I guess that also has some to do from the ableton side, but still... It's disappointing to buy a workhorse for almost 3000 dollars and you can't enjoy a seamless workflow.. I want my trust back from apple...

I've had the USB audio problem all along. Fusion Drive, latest iMac fully loaded. I've upgraded the latest Logic a couple days ago and now the new system. So far as I can tell, for the first time I bought the machine, audio through USB works without issue and it never did before. I recorded 3 minutes and it was pristine. When monitoring the recording while playing there was a long delay between playing and hearing, but I don't care about that because I can monitor the actual sound separately. Try this one out, at least for me it works for the first time.


Audio equipment tested:Korg Kronos keyboard transmitting audio directly from the keyboard's USB out to the iMac's USB in. Lots of other things open at the same time. Perfect recording. Everyone with issues should try this again and see if it is magically fixed. This is the first time in the life of my machine that recording without clipping kinds of noise has been possible.

So you may read for yourself, Vadalino, and as Simon Edwards 1 said, no mention of audio problems, here are the notes:

As of today I am on Mavericks 10.9.3 ITunes 11.2 iMac late 2013 27" with 3TB Fusion Logic Pro X 10.0.7 Motu Ultralite mk3 1.6 build 60625 Neumann KH120a monitors.


I still get the occasional odd distortion/ hiccup even when just playing an Apple AAC ripped CD in iTunes via USB.


Via Firewire it seems a bit more stable than it was (not hard), but not perfect. Sometimes there seems to be an odd 'warble' like listening to an old tape capstan with a flat spot, and the play head on Logic Pro X seems more jerky that it used to be. Under iTunes I get the odd glitch, but not always at the same point in a song.


Edit: at least some of my current problems seem to be in iTunes itself, as I can hear the same "digital clipping" over the internal speakers too.


I mean if you can't even play a couple of songs without problems on standard releases of code, what sort of testing are these developers doing? Certainly not any lengthy critical listening on audio interfaces from multiple manufacturers if you ask me.
