I bought this sound card and it just arrived today. I hooked up everything and installed the software as well as the new drivers. The problem is that all my audio playback is pops, white noise, and miscellaneous sounds; this happens on everything from mp3s to normal window sounds. The manual is of no help and the Hercules website is pretty useless. I am running this on an HP Pavilion 522c and didn't install any of the other software besides that which the sound card requires. This is annoying, and I've exhausted the usual culprits.
