I'm currently having similar problems. I've got dt770 pros hooked up to a fiio e07k USB DAC, and I'm getting small pops, clicks and cracks that seem to get worse when I'm doing something on my pc.
E07k with my ipod: no problems
E07k with jack into pc: no problems
that one little program measuring buffer: all in the green
buffer size in foobar: no change
mich41's and your solution (no similar numbers on any other ports): no change
updating drivers from mobo: no change besides I'm now getting a bsod on shutdown... that's going back to default.
small general things like using 48khz instead of 92khz, changing usb ports, turning off the exclusive use etc: all no change
Are you sure you're disabling the right device(s) which share similar IRQ to your DAC? Perhaps post a screen here so we can better analyze it?
This is mine. The device highlighted is my USB dac, I know this because when you right click it and select properties, then Advanced, it displays how much bandwidth the device is using. When no music is playing it shows 1%, when music is playing it shows 46%.
And as you can see under it there's another device ending in 293A which shares the same IRQ (23). If I disable and reboot (important) that then there aren't any other devices sharing the same IRQ as my DAC. Audio works fine then.
If you find that there are too many devices which share the same IRQ, try a different USB port. When I try a different usb port, then there's like 5 devices which share the same IRQ number as my DAC, luckily I have another port (the one im currently using) which only has one other device sharing the same number.
