Massive problem with audio interface

I have a read this but have not tried it, however i did use carboncopy and reboot from an external USB clone and yes the problrm went away. That statedf yes its a work around but for paying almost $3000 and having to do something like this for a brand new computer is just not acceptable. The long you keep it the less likely you will be able to return it.

Good luck with that approach but it was not for me :-)

Tom,

Yes this forum is good group therapy but for me and the fact i got this for iMac for #$3000 and it does not work as it should just is not acceptable. I would return it while you can and either go with a MacBook Pro or order the new MacPro since at least we know there are no issues with the MBP. Wish you well on your new computer !

William,

Yeah luckily I am more of a hobbyist with audio recording and do graphic art stuff mainly, so I will probably just hold out for a fix, but wanted to throw my same situation into the ring.

I have been talking to the Apple support team all morning, and they are going to call me back too, but I am certain this forum is correct and that my issue has to do with the fusion drive, and I just wanted to log the complaint as well as everyone here in order to hopefully get more attention brought to getting a fix for this problem.

Another funny thing is that when I record audio with the Audactity program (free internet download application for audio) , I do not get the buzz/fuzzy noise, which is weird, but I can't record with that because of the intense unfixable latency of that application.

Good luck!

Hi all,

Just to put this in as well, I am using a SATA hard drive and my sound drops out completely after about 2 min of just listening to iTunes or YouTube using apogee duet 2 iOS.

Works 100% fine on the iPad air.

My sound output is not the problem though, the only issue i am having is a gross digital distortiony sound whenever trying to -record- audio only. All other audio aspects are fine with mine good luck!

I am currently installing mavericks and garageband onto a 64g usb drive, ill boot up to that and see if it works

I think everyone on this post should send feedback and complaints on this issue at - http://www.apple.com/feedback/

We need to get a response or hope for this issue to be resolved, as it is a terrible incovienence that is costing us time and money.

Cheers.

Ok, so after all the tech support (on and off all day) i came to th same conclusion as this forum majority.

I installed Mavericks and them garageband onto an external hd, and it WORKS PERFECTLY.

so the FUSION DRIVE must be the problem.

Even though this is a bandaid, that will allowme to actually record sone audio, it still ***** because who knows when the real fix to the fusion drive problem will happen...

They know though.. At least several upper level techs know about this and are hopefully reporting it.

This guy i talked to (brandon in austin) was really cool and tried to help as much as he could, even though i already knew you guys here had the problem figured.

Fingers crossed they get a "real" fix soon. A MILLION THANKS TO THIS FORUM POST AND COMMENTS.

I did just that just now, yes i think maybe, hopefully that will help expedite if enough folks did it.

I had same issue with fusion drive and solution was just splitting up ssd and hdd. I installed all apps and os to ssd and keep my samples and other stuff on hdd. All works fine and no distortions, pops, dropouts and etc.

Imac 2013, 1Tb fusion drive + focusrite scarlett 2i4 Usb / Virus ti snow

Tested on Presonus Studio One, Ableton Live.

This way even worth it if you're really know what you want to launch faster all the time. I mean what should be on SSD part. For me: os, daw, photoshop, illustrator. Im waiting for apple fixes.

I have been reading reports of people trying 10.9.2 developer versions who say it solves e Fusion Drive problem. Possibly the USB problem as well. Keeping my fingers crossed and not doing anything until it's released...

The 10.9.2 Pre-Release from Dec 19 did not solve the problems entirely for me. Are you referring to this one? There is no updated Pre-Release available in the Mac Dev Center at this time.

I am reading this thread:

https://discussions.apple.com/thread/5659615?start=60&tstart=0

Not sure which build 10.9.2 it is. What problems are you still having?

Thanks,

Bob

with the mentioned Pre-Release of 10.9.2 installed I still encounter high-distortions (like high pitched audio feedback) every other minute which lasts for 2-3 seconds before everything turns back to normal. I don't know whether this is connected to USB or FusionDrive though.

With 10.9.1 it was much worse though with the distortions not stopping unless I switched the audio interface off and on again.

Best

I see. The post in the other thread has the person using a FW interface through a TB cable. Are you using a class-compliant driver? Which USB device?

Bob

When is this 10.9.2 out for the public. I'm desperate to get this sorted. While the fusion drive is an issue it really is not the main issue as documented here changing the drive is the fix, apple will address that issue.

I'm far more concerns apple won't fix the usb2/usb3 audio interface issue that is making recording impossible. Crackles like a buffer size error are far more difficult to solve with all audio cards but who knows which actually work correctly! Mine isn't working and my old computer works perfect in comparison yet specs are a bump all round.

I'm going to try and get older usb 2 kext drivers as I've heard they work from a much earlier version of osx in mavericks. But run the USB ports at 2.0 only losing their 3.0 speeds.

X fingers it gets sorted I hate my old laptop.
