Hello, I purchased Asus STRIX RAID DLX yesterday, I like it so far however I have a major issue. Coil whine like noise coming from my 5.1 speakers. I didn't have this problem prior to the installation of the card. I've read up that GPU could cause this but I've got only 1 PCI-E Slot for the sound card. So I couldn't move the card anywhere else. The only way i can move the graphic card away from the sound card is by installing it vertically. Should I try? Would that help? I updated the firmware too. also tried putting something plastic between the cards, no avail. Also, when i plugin a headset to the combo box interference noise doesn't happen.
