My x-Fi Forte sound card is playing at a barely noticeable volume. When i first got the card it ran like a champ, then i started experiencing a series of loud clicks and pops, and then the audio started going in and out until now, it's current state. I only use the Headphone output jack for privacy reasons. I'm running Windows 7 Home, HP Quad core AMD Athlon Phenon with 4 Gb of ram. Please help email@example.com.
