Hi all I have recently installed a HighPoint 1640 RAID controller, and have it configured to RAID 5 with four hard drives running in the array. since installing the RAID controller, whenever there is data transfer between the array and one of my standard SATA hard drives not connected to the RAID controller, the sound out of my speakers distorted badly, almost like the sound when tuning in a radio station. My soundcard is a Creative Audigy 2 ZS Platinum Pro, with which I haven't had any problems with in the past. My motherboard is an ABIT IC7. One idea I had was that because the RAID controller runs off the PCI bus, as does the soundcard, that ome kind of interference in the PCI bus inself was effecting the sound output? Anyone got any ideas? Cheers.
