Zipper noise and buzz in Scope projects

[Music Manic]

I am currently getting zipper sounds when I move the Scope graphics plus some buzzing when I load Scope effects.
I sometimes get DSP Capacity errors even when the three 6 DSP cards are lightly loaded.

Would this happen if STDM cables are loose?

Any ideas?

Thanks

no, that sounds like an irq and/or a grounding issue...

Wow! quick response.

Would it be internal or external Gary?
How do I isoloate it. It does sound like an earth prob.

Would Sata cables affect sound seeing that they are near the cards?

P.S. I get a pop when I load analog dest to card 3. I think the problem is there but would it be the cable coming out?

Thanks

Getting noise when moving scope knobs or sliders is a known problem. Are you using scope 5 ?

Yes Scope 5.

I think I have both because of that Pop sound
