Massive problem with audio interface

Upodate

Upgrading to new Apogee beta firmware didnt do anything. Still the same problems (dropouts, dist) when listening to a new recording. After this I installed the new Maverick beta dev version and did the same recording procedure and the problems disappeared completely. Now this needs to be tested more to be sure but there is definitely improvements in the coming Maverick version.

biggusDikkus, when you write the issue could come from core audio, i changed my old 2007 imac for 2013 one (the new one) i noticed the internal microphone i used for recording some acoustic videos was muuuch better with the 2007 ..

i cannot use the microphone of the new one .. sounds terrible, especially the guitar, it wouldnt be a problem if i could at least use an external card and microphone .. what i cannot do ! i will send back this **** imac and go back to windows .. at least for 1680 euros you get something decent

OK, here's the update!

As some people have already deduced, the problems detailed in this thread have two separate causes:

1) The "Fusion Drive" issue, affecting new iMacs with a Fusion Drive installed.

2) The "USB Audio" issue, also affecting the iMacs as well as other new "Haswell" computers like MacBook Pros / Airs.

The Fusion Drive problem has been addressed by Apple directly, and the upcoming version of OS X - 10.9.2 - includes a fix. As mentioned above, there is a beta version available now, but you must be a member of their developer program to obtain it legally.

For some people the OS X update will fix their audio interface problems completely. Others with "Haswell" Macs may still be experiencing disconnects/distortion due to the separate USB Audio issue. We recently received code that addresses this issue, which we have integrated into the firmware for the Duet and Quartet. Today we're opening up betas of this firmware, available through our support team. You can find instructions on how to get the beta here:

Hope this gives some clarity on the whole situation, and many thanks for the patience of everyone who has run into this issue with an Apogee interface!

For your Information, I got the following support email by Allen & Heath which confirms the USB3-issue and that this is something the manufacturers have to take care of:

"

Thanks for the message.

We have identified issues with some, not all recent USB3 mac models.

The software team are working on a fix and it will be rolled out in a future firmware update.

I'm sorry I cannot give you a timescale for release but please be assured we are aware on the issue and working on a fix to resolve it."

actraiser .. i really have doubts for the USB 3 explanation, i plug a POD XT (line 6) and it works perfectly, if USB 3 was responsible i should have the same problem than with my presonus sound card ?

i also repeat guys, try to record your voice or an instrument with the internal microphone ... terrible ...

Hey hankboomer,

I did experiment with just internal mic, recording into Garageband.

No problem. Sounds like a built in mic.

While I was at it, I also plugged in an MXL USB.006 condenser.

No problem.

I'll leave it plugged in while I'm out of the office for a few hours and check again.

interesting testimony this tends to prove problem comes from fusion drive thing ...

i am so **** disapointed and frustrated not being able to play music !!!!!

Definitely connect with AppleCare and submit bug report at apple.com/feedback

New version of 10.9.2 beta has been released in the last 24 hours.

Any news about 10.9.2 beta 2 and Fusion Drive bug?

Is there a new version of the Beta?

Yes!

Here the news (in italian)

Http://www.saggiamente.com/2014/01/17/mavericks-e-ancora-da-perfezionare-esce-la -10-9-2-build-13c39/

I installed the 10.9.2 beta that was linked from this forum. Prior to this, I could not record audio successfully in any application -- Pro Tools, Camtasia, ScreenFlow, GarageBand. Today, I seem to be able to record in Camtasia, ScreenFlow, and GarageBand but NOT in Pro Tools. I tried recording to the internal drive as well as setting the disk allocation folders to an external USB 3 drive. In Pro Tools, I am getting the same errors as before--underflow, overrun. So this 10.9.2 bet has NOT improved my experience with Pro Tools, but I am hopeful that I can continue to record audio through my Mbox 3 while creating screencasts in Camtasia and ScreenFlow as it is important to my work in education. If I can record and edit audio in GarageBand for now, it will suffice as I am essentially only recording speech. If I were using this workstation for music sessions it would be a disaster.

My rig:

Late 2013 iMac, 27", i7 3.5, 1TB Fusion Drive, 16GB RAM

Mbox 3 Pro

Pro Tools 11.1

Anyone else have success in Pro Tools with the 10.9.2 beta?

Strade, have you tried the internal microphone with photobooth ? just to see if there are statics and other metalic noise ?

There is a new 10.9.2 beta now, but it's only for developers.

Any news about this last beta?

I found one fix, not sure if it will solve problems but solved mine. I am like most here with a relatively new iMac from last year times of RAM fast processor and after upgrading to Mavericks have experienced exactly the issues listed in this thread. I spent an exhaustive time looking for any irregularities ended up reinstalling the system added a new user and talking with folks at Apple.

I finally found by simply deleting the application Boom (Globaldelight) solved every single audio problem I was having. There seems to be pretty large group of people using Boom experiencing the same things. The application seems to suck up processor and thereby causes delays and other audio issues. I have loved using this sound app, but it is simply not worth it given the audio issues system wide it causes.

Hope this helps,

Dylan
