RME Multiface Noise Issue

Hey there, i use two RME MF II in my PC. I haven't worked with music for a bit and i now do have some issues with digital (?) noise. Please see this soundfile:

I have the issue on both my Multiface II. It doesn't matter if they are both connected or just one is. The noise output is -51db



To be more detailled here is a little description of my setup:



2x MFII -> the first is connected to the second via SPDIF (Professional) & Wordclock

1x Fostex VC 8 connected to the first MF II by ADAT & Wordclock

1x Adcon Marian connected to the second MFII by ADAT. The sync is also ADAT



All LEDs that should be lit are green. No red, no nothing. Keep in mind: the noise also appears when either Multiface is connected to the PC. So it can't be an issue with the peripherals.
