cracks in the recorded audiofile

[sgans]

Hi, I hope, someone can help:
The problem: The sound input signal via Matrox hardware (XLR) is OK, but during (voice-over)-audio-recording there are short cracks in the audiofile - sometimes less, sometimes more. Sometimes in a long file there are no cracks, sometimes they appear steady like a tick of a fast clock. I recorded the audiofies to different harddiscs (qualified for HDTV-video) on computer and external. There seems to be no coherence.
At my last VO-sessions the cracks occured more often, so I had to make an paralell sound- backup to a hardware-recorder (not a very professional working...).
The soundprocessor and the Mic & cables are tested, they are innocent... No virus-tools or parallel audio-tools are installed, even the Windows defender is deactivated.
Of course I deinstalled Mtx.utils totally (manually removing of the mvk*-files, CC registry cleaner) and reinstalled the software as well as I de/reinstalled Adobe CS/CC, additional with the Adobe CC Cleaning software (at first installing Adobe then mtx.utils).
For me it seems to be a problem of hardware, the Matrox MXO2 Rack or the computer. Do someone knows this problem? What can I do to encircle and fix the problem? I have rendered a mp3- soundfile to demonstrate the "caracter" of cracks - perhaps someone want to hear: ask me...

System:
- Windows 7 Professional, Service Pack 1
- HP Z400 Workstation, Intel Xenon CPU W352 @2.67 GHz, 16 GB memory, 64 Bit OS, GeForce GTX 650 Ti
- Matrox MXO2 Rack, MAX (2011-08-30), Mtx.utils 8.0.0.15342
- Adobe Premiere CS6 (6.0.5) as well as Premiere CC 2015 try-out-version. Preferences-Audio hardware: Matrox ASIO Driver..., XLR

Thank you in advance...

Does the issue occur if you reboot the system?

Can you try previous Mtx.utils 7.7.2.2018 drivers with Adobe CS6 and see if this works?

Thanks for your quick answer!
Does the issue occur if you reboot the system? > what do you mean? I start the computer, start premiere and have the problem. Even I restart both the promlem is still there...
Can you try previous Mtx.utils 7.7.2.2018 drivers with Adobe CS6 and see if this works?> I had the problem with a previous version (don?t know which version) and full of hope I installed the new one - successless. But OK, I will try it and I'll report you the result...

Thank you Sam,
I deinstalled Mtx.util 8.0.0.15342 and installed Mtx.util 7.7.2.2018 - and it seems to be successful...
As I wrote I had an earlier version of utils with the same problem and therefore I installed 8.0.0...
So I hope there is no reason to contact you the next days (months, years...?)

Glad to hear all is working well. We have reported the issue to our engineering department.

We will close this post but let us know if you have further updates in the future.
