Using both front and rear audio outputs from my motherboard, there is a horrible high pitched interference. If I change the audio settings from headphone to front speakers, it reduces, but is still very much present. It's totally distracting and makes listening to anything using decent headphones or speakers annoying.
It also seems to respond to mouse movement.
I've tried unplugging everything attached to the machine, USB, DVB-T aerial, video etc, but none of it makes any difference.
I'm using a Gigabyte MA78GM-S2H 780G motherboard. I have the latest audio drivers, though changing makes no difference.
I think perhaps there's some sort of ground loop going on, and I've tried to narrow it down as much as possible.
One thing I haven't tried is disconnecting the front panel audio.
Any other ideas or suggestions for getting rid of this problem?
