Friends, I bought a brand new Creative SBS A500 5.1 speakers and Creative Sound blaster 5.1 VX. Before installing card, I checked the speakers with On board stereo audio. It was working fine except 5.1 mode not enabled. But after installing Creative SB 5.1 VX PCI, I am not able listen to any sound at all properly. Audio is played with lot of crackling and popping sound. Even a ding sound is played as d..........i..........n..........g.......... My system config below. Core 2 Duo E4500-2.20GHz 2GB RAM Win XP Professional SP 2 (5.1.2600) D945GCNL - Intel Motherboard Creative Sound blaster 5.1 VX PCI Model # SB1071 Product link : I could not post link, you can find it with google easily by searching "creative sound blaster 5.1 vx". As I checked with system requirements for the product, it matches with my PC configuration. I did not find any issues reported against this product and I wonder about that. Hope I stated my problem clearly. Experts help is much appreciated and thanks in advance.
