UMC404HD glitching

Any one help with this knotty problem?


I have a new pc, spec below. My UMC404HD now glitches then cuts out. I have tried all the diagnostics I can think of but to no avail to include:


Buffer sizes


Changed motherboard from H310 to Z390 chipset


Removed video and wifi cards


Disabled all onboard audio drivers.


Removed all drives and replaced with ssd from old machine.


Tested UMC404HD and USB cable on another pc.


Example of glitching in link below.


I've run out of ideas!


Any ideas?
