Massive problem with audio interface

Update on my MBPr with Behringer UMC204:

Installed 10.9.2 beta as per Anthony's suggestion.

No change.

Reinstalled OS via recovery drive.

Suddenly, interface worked with Garageband.

Attempted to play a song from iTunes.

Song wouldn't play (time counter wouldn't move, as if music was paused)

Switched to built in speakers via system preferences.

Song suddenly played.

Unplugged and replugged interface.

Same crackle noise and drop as before.

Went back to Garageband.

Interface failure and dropped after a few seconds.

Wondering why it worked at all.

I've also contacted interface manufacturer to inform them of this widespread issue.

@Anthony: Where's that Youtube vid you mentioned?

im sorry to hear that dude. i can only give suggestions. did you download the latest drivers for your device for mavericks ? if so try disconnecting the device, uninstalling any previous drivers, reinstall updated drivers then plug device back in. alot of times the old drivers can interfear . i had to do this myself. but i cant stress how important it is to have fresh updated drivers for mavericks. it will not run correct if at all without them no matter what. and the messed up part is alot of these companies are slacking on updating for whatever reason. some are going to try to make money off of this situation and say that its not possible and only their NEW interfaces are compatible which is b*llsh*t . Also if anybody is using Logic pro X the newest update is 10.0.6 which was just released and they fixed alot of issues also. 10.0.5 was garbage and had interface problems out the @ss.

As for the video it was done before i figured out that splitting the fusion worked for me and also the new beta fixed my problems too. it was more of an awareness video to help spread the word and to push people to complain to apple as much as they can so that they would get it fixed sooner. http://www.youtube.com/watch?v=ZV0LqdL1h6g

i would try as many things as your patience can handle without throwing your machine into the wall. when downloading driver updates from the manufacturer site alot of the downloads will come with an uninstall file also. i used that to clean all the older info out and reinstalled a fresh driver like i said earlier and that helped me alot.

any info i come across i will report back here asap . i want everyones machines running proper and for everyone to make beautiful music or whatever your guys passions are. but for now just make a time machine and try everything you can. but i wouldnt go as far as exchanging your machine just yet because it definitely looks like thhis problem will be squashed very soon.

I have an 27" late 2012, i7, 4x3.4Ghz ivybridge, 3TB FD, 24 of RAM and a Scarlett 2i2.

Installed Maverick first then Scarlett driver (not class compliant). I only use the Scarlett to play audio through Mplayer X and Firefox (Youtube and the like). No recording. Playback produced severe gapping and distortion at first. An old win XP pentium would have done better. Tried to play with sample rates, core audio, nothing worked. I finally gave up to try since F-Rite promised to fix this (meantime use class driver blahhblah.......but I did not).

Did the Update to 10.9.1. Though I can not exactly remember the date, since some weeks, the problems are just......GONE!. Playback is fine. But why? If I update once 10.9.2 is available - will the problems come again?

Besides: During researching the USB-Interface-Issue, I found out that you obviously need to buy extra software to avoid resampling during playback or you must change the s-rate manually in Audio Midi Setup to match each media files rate. Although I must admit I cannot hear the difference if audio is resampled (my ears are not best in class) - this is a shame!

Come on, Apple!

Thanks Anthony.

As I stated earler, the manufacturer said no firmware/drivers for Mac, just plug and play.

And the unit is one of their new models.

I guess this took them by surprise like it did many others.

I'm stirring that pot now.

I'll return with any updates.

Good thing I didn't prematurely sell my trusty old 2009 MBP.

after all that why not try the beta 10.9.2 ? youve already been through **** and back brother .

Here's my two pennies on the subject:

I, and all experienced pro's, know that new technology always leads to unforseen issues.

If you are professionally depending on your Mac (or any other tool), you will only make the transition to a newer version after thorough investigation and testing.

So, I can live with the audio issues caused by combining a new OS version, a new and promising storage method (fusion), new USB versions and the like.

What irritates me is that Apple leaves us, a very loyal community, totally in the dark. We cannot do anything else than relying on rumours, whispered secrets, individual engineer opinions and smart fellow-users, helping us with workarounds.

It's about time Apple realizes that issues like this are not threats, but opportunities to show they care. It's so simple: Apple, F%##}£¥? communicate!!!

Why answer me? I'm just giving you the link to contact Apple. I couldn't personally care about your problem.

Thanks Anthony for all of your work and persistance. It appears to be a software issue. I'm sure that Apple is working on it. Pete.

not a problem. i just want everyone to be happy with what they paid alot of money for and ill contribute anyway ican. i pulled this big ***27'' imac out of the beautiful box it came in and i might have caught a stiffy it was so sexy . i hook it up and it boots up and ready to go in between 12-14 seconds . i go to use it for my music production and BAM i got slapped in the face with a major Apple flaw. i imagine most of you guys fealt the same way and it really *****. dont worry guys we will be doing what we need to do with these beast machines in no time.

Good News: I can confirm that OS X 10.9.2 fixes the issue with the Fusion Drive and MBox Mini (and possibly other USB Audio devices).

My Hardware:

27" iMac, latest version, 3.5 GHz i7

3TB Fusion Drive

8 GB RAM

Drobo 5D hooked up via Thunderbolt

2 24" LED Cinema displays, one directly connected to Thunderbolt, one chained off the Drobo's second Thunderbolt port

MBox Mini connected via USB on Cinema Display that is chained off the Drobo

Logic Pro X 10.0.6

Previous symptoms:

Audio drop outs after a few minutes in all sound related applications

Audio degradation in Logic

Both iTunes and Spotify Apps could (and often) froze machine (no mouse or trackpad or keyboard input until hard restart)

None of these issues occured when switching all audio to go through iMac's built in speakers.

Last night I installed the Mavericks 10.9.2 Combo Update (13C32) available right now only to developers, but you can find it, it's out there.

Everything works just fine now.

Stress test:

Before I went to bed I put a large Spotify playlist on shuffle and repeat, did the same for an iTunes playlist, and looped a 32 track Logic project all at once (yes, this sounded horrible!) and turned the volume down on my MBox Pro. When I woke up and turned the volume up on my MBox Mini, all was still playing through my Event 20/20 speakers. I have worked all day today in Logic and it works great.

I thought I was going to have to send my iMac back for one with just an SSD or perform the Fusion Drive split that people were talking about, but all is well.

Hopefully this update will be released soon for everyone.

Hope this helps. I personally was heartbroken for a couple days as my new machine was pretty much useless and I had already given my awesome early 2011 quad-core MacBook Pro to my brother.

Keep the faith 🙂

Hey Johnny, am still experiencing issues this end. Got a 1TB fusion drive & using a Focusrite 2i2.. Does ANYONE know of ANY interfaces that are having no issues at all.... with OS X Mavericks?

Titus - did you install the class compliant drivers from focusrite for the Scarlett? (then reboot). I have the exact same setup as you, Mavericks, 2i2, 10.9.2 beta and everything works.

Hey McNezza, I don't have 10.9.2 beta... Where do I get this dude? Oh and yes I've run class compliant mode. 🙂
