Thanks Louis! Looks like it'll have to be returned to the shop.
The only issue with it was when it was being installed into the PCI-Express slot. The connection to the MB was very very loose while the speaker cables were being changed around. This caused the sound card to be turned on and off when the power was on... so had to put it in the other PCI-E slot.
Didn't seem right at all.
Could that have interfered/affected the bass/subwoofer output of the sound card?
