El Capitan USB audio problems.

I have the same problems with NI Traktor Pro 2 combined with a NI Traktor Control S8 and already with a NI Audio 8DJ Soundcard. The Problems to emerge since Yosemite. No solutions from Apple support! Every weekend the same Problems with the audio distortions and dropouts!!!

Hi All,

Every weekend I am having 2 live gigs and I am having the issue each time.

NI clearly responded me that the issue is happening from Mac OS audiocore driver and not NI.

How can we make apple solve this issue?

Do you think that submitting a ticket can solve? I don't think so.

Why Apple is not hearing us? Shall we put this on to change.org ? (many companies fixed issues with this way in the past)

Possible you could get the latest Beta version? I am not sure what it takes, may be worth it in your case. For me I just a use a PC for Music at the moment.

Coincidently last couple of weeks, I switched to Beta versions with NI Supprt Team's suggestions.

They told that with Beta's they see the issue is resolved.

So they asked me to switch and I took the risk and switched to beta3, then beta4, then beta5 and now beta6 and had a chance to live test all of them each week.

But nope, not solved it 😟 So don't install beta for now...

Once I thought that it solved, on a Friday night gig nothing happened but on Saturday night, it happened again.

Today beta7 is released. Now installing with a huge risk beta7 and going to live gig in 4 hours.

Wish me luck but I have no faith in this update as well. In the release notes there is no mention about audio issue improvement.

At this point I don't there will be a solution for USB Audio in OS X.

After several releases Apple continues to ignore the problem. 10.11.4 is about to be released and most problems are still there in the last beta.

This a shame and for me at least it renders OS X almost useless. I can't work under an OS that drops or distorts audio randomly.

What a disappointment Apple ... Can't you hire a team to resolve these problems ? It was't there in Yosemite... I can't be so hard to fix!!!!!

Last night after 4 hours of playing a gig with NI Traktor Scratch Pro 2 and a NI Traktor Kontrol S8 cames the first distorted audio drop out!

Shame to Apple. I bought a MacBook for 2000€ with a OS X system full of audio problems!

Apple just dropped the final release of 10.11.4 and this issue is said to be fixed in the patch notes, "Fixes an issue that caused USB audio devices to disconnect."

No luck for me with NuForce DAC3 Async

Thanks but I don't think that it addresses the issues that we are having. We don't have disconnection problem but sound distortion.

I will install tonight and test it.

Oh well the person who started this thread was having the disconnect issue and so was I (I haven't tested it yet with my DAC though)

Sorry, missed that one, you are correct. Hope this update solved his/her problem.

I will say that 10.11.4 has solved the issue of occasional bursts of static I had been getting through my AudioQuest Dragonfly USB DAC when playing music via iTunes.

Hi William, do you imply that your issue is fised with the latest 10.11.4 final version or it was already fixed in the 10.11.4 beta versions already?

Same problem with MacMini Late 2012 and Asus Xonar Essence One, last update didn't fix this problem. Apple, wake up!
