Massive problem with audio interface

I don't think you should have any problems. From my experience, the USB Audio issues were a software issue with Mavericks and the Fusion Drive. An update to the Mavericks software took care of the the problem for me. In addition, you have a Fusion drive, so you should have not issues regardless

OKay thanx guys. I guess i'll have the latest update installed or it will be installed when i start things up/ configurate.

glad i went for a SSD anyway. And should i run into usb related issues i guess they can be resolved.

can't wait to try that sucker out.

We must pray to the gods of Yosemite. I will say that I am not having audio streaming issues, like a radio station streaming app like Radium or YouTube videos. But the recording issues through USB I find consistent across different apps. Updates to Mavericks have corrected issues I've had with a USB microphone, the Blue Spark Digital mic.

What I find interesting is when I go to the Apple store or talk to anyone from Apple on the phone, no one knows about these issues we discuss here. There are now 47 pages of complaints in this one discussion thread but any sort of tech support seems to be clueless that the issue even exists. That ****** me off.

I Agree. It's pretty widespread, but apple doesn't really give a reaction.

I've thought about waiting for yosemite allready being installed but people assured me the update to yosemite would be effortless and problem free.

i'm skeptical though

Make sure that you report the problems you are having to Apple through their Feedback pages. The goons at the Apple Store are generally not that clued-up.

Anyone who claims any new OS will bring you no problems is a fool. The only question is whether the problems that Yosemite brings will affect the parts of the OS that you use!

After having a similar problem (Stream/computer lockup for moments on my Haswell based rMBP) I have been working with Native Instruments for months.

FINALLY i got the right guy and he told me that the Haswell based Macs have a fault in their USB3 chipsets that stops them from working correctly with many USB2.0 sound devices. After months of them having me use different latency settings, and other malarkey, I finally managed to get a tech who gave it to me straight. Native Instruments has been working with Apple to get this fault addressed, but being as this is effecting legacy products more than contemporary ones, NI does not expect resolution soon.

Okay, well hopefully they will work it out.

Am i to understand that USB 3.0 and Thunderbolt interfaces should work just fine?

Thanx

From what they told me, USB3.0 and Thunderbolt devices should work fine.

In my case the Native Instruments "Audio 2" was what was running into the problem. But I was assured that I should avoid the issue by using the Native Instruments "Audio 2 MKII". I would have been pretty angry to get the "just buy the new product" answer, but being as I already had an MKII, I didn't have much reason to gripe.

I'm going to call Apple, though, because they had assured me on a support case that I'd opened that this was definitively the Application Developer's problem.

You'll need to do this each time you reconnect your audio interface, but it should solve your problems?

Open Applications and then Utilities. Open Audio Midi Setup. Make sure your interface is selected on the left, and then under the "format" drop down menu, select 96,000.0Hz. The clicking will be gone.

Late January I added my voice to the many people who had experienced issues using audio with a late 2013 iMac with a Fusion drive. I had seen many reports that subsequent patches to Mavericks had fixed tho issue. I had split my Fusion drive which had fixed the clicks and drop-outs. Yesterday I finally got around re-creating the Fusion drive in the hope that the original problem was resolved. And I am glad to report that it has fixed my issues! I finally have the iMac I was meant to have bought. Been streaming for iTunes for the last two days and did some basic playback testing with Cubase. So far, no problem whatsoever. Note that I am using a Firewire audio device (Phonic Helix Board 12 Firewire MKII).

Hi!

I figured this was a 10.9.5 problem as my 1818VSL drivers were compatible with 10.9.4 at most.

I own an iMac 2011 with no fusion drive.

I did a complete format and reinstalled 10.9.4 from 10.9.5 and still the same problem.

The only solution I have right now and I have tried everything is to skip the driver for my interface.

The 1818VSL is class compliant so it's possible to run without a driver.

I get no input monitoring only software monitoring which is a real shame but it's working. No clicks or anything just beautiful recorded audio.

For those of you who has the ability to run your interface without a driver I suggest you do.

In the meantime, Apple:

This is a total outrage, disappointment and unprofessional way of handling this.

If you insist on making designer electronics then for f**k sake make sure the "guts" work first before you even consider the body.

Studio's are at a halt all over the world because of your Airplay, Notification, Facebook crap. Make a system that works and don't even bother catering to the makeup blogging self involved tweeters. They have apps for that. Its not an ideal system requirement.

Fix.

New info:

10.9.4 + Combo update + legacy audio driver (not current),

working 100%.

1818VSL interface.

jonnyk, this whole thing is breaking all our hearts, do you know if apple ever released a fix for this? Are you still running your partitioned system?

Hey, does anyone know if a Thunderbolt audio interface will work well when USB 2 won't? With Yosemite having the same issues I'm ready to break down and get a new audio interface. The Thunderbolt interfaces are pricey but worth it — IF IT WILL SOLVE THE AUDIO ISSUES!

Hello,

I've just found this thread and immediately thought about my problem as well, but I have late 2008 Unibody Macbook with 8GB RAM and 7200RPM HDD.

The hole problem is that when I connect my DAC over either USB or optical toslink I can hear that distortions and clicks, especially when playing 24/96 or when I pause the music. Do you think it might be related to this core audio bug? I can hear the same on 10.7.5 as well on Maverick - I have one small partition on the same drive with both.
