Hi,

I have an SDS-9 connected to a PC which has a 6 channel
(soundblaster) external audio interface.

The problem is that I am getting a constant high pitched
interference, and other noises when I move windows around on the PC
screen. There is at least 1.5 metres of separation between the PC
and the other boxes.

The interference is identical across all channels, so in a mono mix
it is multiplied six times becoming quite noticeable.

I have just made new cables in hope of curing the problem, but it
has not helped. I cannot see any grounding problems.

Does anyone know how to solve this problem please.

Thanks in advance,

Richard.
