I’ve got the logitech X-530 system connected to my on-board Realtek sound card.
This morning, the speakers just started buzzing (with the PC turned off). I have tried all sorts to get them working properly again but no joy. They have been working fine for the last 6 months!
If I try the green plug into my ipod they work fine. But as soon as I plug them into the PC they start buzzing. I have also tried a PCI soundcard but the same thing happens.
If I unplug my PC and Monitor at the mains they stop. But as soon as I plug them back in they start buzzing again. If I plug them into one socket and the PC into another they still buzz. My old speakers work fine.
Are they faulty or is my PC or Mains to blame?
