I've had a MOTU 8pre for almost 2 years. It worked great for quite a while. This fall it began to disrupt my whole computer. I run XP Professional on an Intel board, Intel Quad Core processor, 8 gigs of ram. Freeze-ups of any type of program that uses audio. My DAW is Cubase SX3. I resolved some of those problems by getting the updated drivers, etc. But now...I'm only getting 2 functional channels out of the 8pre...with channel 2 working when it feels like it. Some crack, snaps, and pops when it feels like it. I've probably tried calling MOTU about 50 times or more...either busy or no answer. I've tried to use their email tech support, with limited response or help. One thing that's come to mind is that maybe my firewire port on my computer has gone bad. It's built into the motherboard. Any thoughts?
