| Unwanted digital noise (Not the standard noise floor) from studio monitors |

I had a similar digital sound on my audio which changed depending on mouse movement and what the PC was doing. It went away as soon as i switched to using the optical input on my speaker amp instead of phono jack. So i assumed it was just a ground loop coupling switchmode psu noise onto the line, which would vary with cpu load. |

And safety should not be a problem since all the gear is grounded in their respective power cables? I also should add that it seems like there is trouble in the communication between the firewire sound card and the computer. No audio plays, spotify or other audio software won't even play and the volume icon on the taskbar sometimes just shows a red warning symbol. Could this be some kind of power ground trampling a signal ground or the likes? Excuse my ignorance if this is total nonsense, just thinking out loud. |

Get analog mixer ( without USB ). Stop using USB for audio. Get ground in your power from the wall. Use a PS2 mouse. |

The soundcard i am using now has a firewire connection and its own power supply. |

And I suspected that this may be the case because it looks like the monitors have plenty of ground loops inside, between the various boards connected with cables and screwed to the metal chassis. That's :-- for Yahama. --- End quote --- He says his records sound like shit. You dont record tru your speakers right ? Cant blame Yamaha here for. |
