Hi All,

At this guess it might be that there is some kind of electrical interference going on, which would certainly account for the squeaks and squeals. Alternatively, this may be caused by clipping, where the output is overloading the amplifier and causing distortion. If possible, try and take the outputs from the board into a PC (or Mac) sound editing application and see what kind of wave forms you get.

HTH,
