Hi lambros,
My first thought was that it would be an electrical issue like you
said. Power regulation being possible, induction noise from a nearby
power supply, depending on the sensors - noise from the input like
light, or acceleration, etc.
Did a UPS solve the issue?
I've also seen some strange issues with the built in spdif on newer
MBP's I'm very curious about this. You didn't mention the
interface. Is it by chance a MBP? Do the spikes still exist with a
different interface?
