Q: Massive problem with audio interface

Thanks  I will check it out.

Funny that everytime an update comes out, they say to focus on the mail...

And other mumbojumbo (execpt for the graphicscard) but nothing on the sound.

They don't give a ****.

FINALLY!! The 13C59 beta has fixed it completely. No dropouts, no clicks and pops, everything working well.

That's great news.  Now I just hope they'll release a final version soon.

You got a Fusion Drive Markkittus?

Hi all,

Add me to the list.

Just got my brand new 27" iMac with 3TB Fusion Drive.

Yep, got terrible distorted audio after a minute, with it then fading away.  Using a Yamaha USB audio interface - Audiogram 3.

Let's hope this fix gets released soon.  Am currently just using the built-in speakers inside the iMac.

Well I hope that's the case! I just received a new 27" iMac with 1TB Fusion Drive to replace a late 27" 2012 iMac with a similar 1TB Fusion Drive which I gave to my son to replace his aging iMac. Kids today don't know how lucky they are! Any way, I digress. The first iMac was upgraded to 10.9.1 and worked flawlessly with a FireWire duet attached via a Thuderbolt connector. New machine on the otherhand displays all of the audio issues mentioned in this thread. So obviously something in the hardware changes introduced in October has caused this problem and by the evidence provided by those who purchased SSD only and HDD only systems it would appear the new Fusion drive is the culprit.

Yes, I have the fusion drive.

I have to say, that, everything in audio works well now, BUT i'm having issues when open finder from the dock, it don't opens. But well, it's a beta, and I really prefer entering finder by clicking my HD on the desktop than use the iMac for facebook only

So: 13C59 -> Audio problems solved for me, and finder problems

Returned my late 2013 model 27 i7 imac with 3tb fusion due to the audio problems described here, purchased another imac with exact same build except with 3tb hdd instead of Fusion.  Everything works great.  Looks like the fusion drive was the problem causer, at least in my case. 

I took my late 2013 1TB fusion imac to the Apple Store and had it rolled back to Mountain Lion

Recording issues seem to be resolved for the time being (using Mbox 2 mini and Ableton).  Hope the rest of you folks get your issues sorted one way or another, definitely a disappointing experience.

I have an update.  I swapped out my latest model imac/fusion for a macbook pro.  

Things are certainly running better - but I still do have constant audio distortion with a Fireface UCX running via USB.   I tried running via a USB hub, via the thunderbolt monitor and directly into the MBP and I still get a consistant distortion on audio output.  

Funny thing is the distortion is in Logic and iTunes, but not when I play audio from the web.

Hoping that 10.9.2 will help.   I also have a friend who's using the Universal Audio Apollo Twin Duo via thunderbolt and says its working flawlessly with latest model MBP.

I imagine that there are USB issues as well as Fusion drive issues as mentioned in another thread on this site.

Some more updates by me using the 13C59.

Audio working perfectly.

Finder not working if opening by the dock, must open the HD from the desktop.

Issues and need to reboot when the iMac turns on the sleep mode.

Hi can you pls tell me where to download 13C59?  OSX86World doesnt seem to work for me. thanks in advance.

Hey everyone Can you again confirm that 13C59 build solves the audio issues? and also any safe place to download this beta? I cant seem to find one.
