Pops and clicks on a Windows 7 64 bit system

    yea, thanks for the reply! The tuning tips are well know to me as I go far beyond those measures to get waaay more power out of my machine as you would with those few tips ;)

    I've got an average of 20 µs driver latency without a single spike.

    Latest firmware is installed as well as the newly released 3.1.0 driver, that has been a beta earlier.

    In the sound prefs everything is deactivated and the stereo mix is not existant for some reason, but nothing to worry about that.

    the only thing, that is on, is the main out of the KA 6!

    hmm :/

    It's odd, it seems like these clicks an pops get triggered by tracks with bad mastering and lots of high freqs!

    I already switched speakers to eliminate this option, too.

    hmm, that sucks so much since I never had a product from NI, that was not faulty somehow

    For me it seems to be every other driver release with the AK1 is bad. Like the last release of 3.1 is horrible. I get random crackles with WDM and sometimes ASIO. Also today I noticed that things just sound off and I was also getting alot of crashes in ableton when tweaking audio effects.

    After uninstalling 3.1 and going back to 3.0 I reloaded the crashed set, set the effect (which was an MFM2 preset for ping pong ducked delay), turned the phaser effect back on and it sounds normal. With 3.1 it just didnt sound right, though I have no idea how a sound cards drivers would affect that. Also doing things that would previously cause a crash dont now

    I've just upgraded my MB, CPU and RAM after my old MB died.

    I now am also experiencing similar problems. Playing back from Cubase is fine (ASIO) but watching YouTube clips or today I was going through one of the macprovideo courses, best way I can describe it is it sounded like a scratchy dirty vinyl LP, crackling all over the place that got worse and worse.

    Finally I pulled the USB cable out of the KA6, waited 10 secs and plugged back in.

    This has fixed it for today but I suspect it will reoccur.

    I have the latest firmware and drivers from NI

    Asus P9X79 MB
    Intel i7 3820 s2011
    32GB RAM
    Tagan 750w power supply
    Evga 4GB GTX 670
    Various SSD and hard drives, most SATA 3, one SATA 2
    Antec 1200 case
    Windows 8 pro 64

    Worked perfectly with my old gigabyte DS4 motherboard

    Edit: when I built this system I reloaded windows from scratch, I also made sure I had the latest drivers. I installed the latest NI drivers which were newer than on my old system, reading the previous post, I think I will try going back a version to see if it fixes it.

    So I'm bumping this thread.

    I bought KA6 a couple of days ago, running similar hardware, win7 x64 and have the exact same problem. It's maddening!

    Hey NI, are you going to fix that in the next update? Please tell me you're working on it. I'm thinking about returning this.. please save me the trouble...

    Well I went back to the only other non 3.10 driver i could find on their download section (3.0.3) but sadly the problems still there.

    I currently have Driver version 3.0.3, Firmware 45

    It's really weird. Starts off fine, gradually more and more crackles and pops appear, I simply unplug it's USB cable, plug back in and all is fine (for a while).

    This is becoming a real pain now :(

    I REALLY hope NI are looking at this thread and taking it seriously. I wanna keep my unit, but this issue has got to go.

    Can someone from NI please tell us if you guys are working on a fix?

    unfortunately i shall have to add my own horrible experience with exactly the same problems that every one else above is having ...
    apparently there is no fix (other than stopping and restarting the audio device in W7 manually) ...

    can any authorised NI person please give us an insight ? pretty please ?

    exactly the same problem.

    Anyone who found this thread while googling for the problem, please register and post here.

    We need to make NI know this is a serious issue that affects a lot of people..

    Same here, and only for WDM Audio as well. No Problems with ASIO even when using lowest buffer-settings.
    Since there was no reaction from NI in the last few months regarding this problem I am thinking right now of selling the KA6 and buying a different interface.
    At least it would be nice to know if they are working on it...

    I am on windows 8 64-bit and i'm having excatly the same problems with 3.1.0. And the 3.0.3 drivers kept crashing my computer randomly. So pleeeeaaassseee new drivers, i really want to start using my interface.

    Running a Windows 8 x64 system, and I'm running into the same issues. The iTunes application seems to be the worst, with the new Windows Music application being a little less annoying, but still there.

    Then I remembered never hearing any of that on my Windows 7 or Windows 8 loads on my laptop. On that system, I used a USB 3.0 ExpressCard 54 adapter since the stock USB support just couldn't seem to hang and had other issues. So, I switched to my front mounted USB 3.0 port, and it's fine. Still using the stock drivers from the install disc as we just moved and I didn't get the KA6 installed on my main workhorse yet (Dell P990x with 12GB RAM at the moment). Also, there was a significant gain in output, and that's with a 2TB external drive connected to the back USB 3.0 interface. I have a great deal of PCIe data running through this system (former Microsoft field engineer and now a platform developer, but used this box for server virtualization in the past) with 5 external drives in an enclosure, 3 internal, and various other bits and pieces.

    So if you can, try a real, GOOD USB 2.0 or 3.0 card and give this another shot.

    A week ago I wrote a detailed report to the NI tech support, but today is still not replied.

    I have a very good workstation, I have not delays or latency. Using Ubuntu Linux the KA6 has not problems, but Linux drivers only supports outputs (no inputs available) and, obviously, there are no Ableton Live.

    I just ran that tool on two systems, and just like the old DPC tool that "worked" in Windows 7 it basically indicated that neither system can handle real time audio in any way. Clearly, the ASIO driver shows that's wrong, and the best part is the worst performance seems to be recorded by the stock USB driver and, like your second log shows, the NVIDIA Windows Kernel Mode driver record the worst event times and total execution time. If I had more time I'd consider a realtime trace with several counters using xperf, but also a general check using PAL to get the report would be good too.

    Some good starting points here:

    So I'm on a brand new, modern, powerful PC and the problem has gotten WORSE! How could this be?

    Come on NI, do something already!

    It seems that mine has also gotten worse, and i havent touched it. (also on a brand new computer, 3770k and so on)
    Also having some direct monitoring problems, but at this time i just want it to work for basic home use.
    Have tried every recommendation, and tip, and all usb 3.0 and 2.0 ports on my computer...

    Any day now...
