Topic: Switching to multi processing causes CPU spikes and audio clicks
I'm having the following problem using a HDSP MADI PCI card in my core2duo pc:
everything is working spotless, and has for a year now, but I can't enable multi processing (to take full advantage of both processor cores) in Cubase SX3 and Cubase 4. When I turn this feature on in Cubase, at first playback seems to be ok, but after saving or switching projects it seems the processor schedualling(or how else you'd call the way in which the system sends data to and from the CPU?) somehow gets messed up and I start getting CPU spikes and audio clicks. This happens even in small projects with just a few audiotracks.
I've always suspected the onboard IDE controller to be the cause of this, but needed it for my DVD burner and system disk. Recently I've upgraded these to SATA devices and thought it would be a good time to try multiprocessing again. I've disabled all controllers I don't need in BIOS and did a complete re?nstall and optimised the system in the usual way, but still the problem persists.
I'm kind of running out of options here, so if somebody has any suggestions I'm dying to hear them. Thanks!
Best regards, Wessel.
