I'm having some problems with some (low) interferences sounding through a Focusrite Scarlett 2i4, a pair of KRK Rokit 5 and a new high-end PC with Windows 10. The sound is this:
It's not that loud, I've raised the volume so it can be perceived better, but it's constant. The noise appears in the monitors constantly during playback, but not in the headphones. Everything is connected using balanced connections. Recording guitars (connected using jack cables) it can also be heard through headphones if I turn up the input volume of the guitar. Microphones plugged with XLR cables do not make any sound through the input (tested with headphones, where there's only noise using guitars and jack cables).
Edit: seems like the interferences react to the mouse movement.
Tests that I've already done:
- With everything plugged in the same place, I've tested it with another PC that I have in the same room, just connecting to it the usb of the Focusrite and in that PC the noise disappears.
- I've also tried to use the power-supply cable of that PC in the one that has the problem, but the noise still remains.
- Finally I tested it in my laptop, connected to the same strip than the rest of the things, and there is no noise.
I'm not sure if it's a problem of Windows configuration (the sound appears after the BIOS) or a problem with the power supply of the computer.
Thanks in advance.
