If it were me, I would try narrow down the cause.
Can you hear that noise with headphones without the RME plugged in to your PC or Virus?? (totally remove the RME from the room).
That sound was very faint so maybe it is hard to do.
Next, can you hear that noise with the Virus plugged into your RME but not into the USB of the computer??
When you answer these you can say Yes or No to 'does the Virus make this noise all the time?'
Then you could consider work arounds like. Try an analog mixing console between the RME and Virus, also try passive DI boxes between the RME and Virus. (GRS hears googling of passive di boxes).
