I found the problem creating the static on playback. It has something to do with the speaker connection to the sound card.
Try this, unplug the jack from the audio out on your box and record a streaming audio. Plug it back in to listen to it.
It should be clear. I've tried just turning the volume off and that doen't help. I've also tried both front and rear audio out
and that also doesn't matter. I haven't tried reseating the card. Sound Tap works great without the speakers plugged in.
Good luck.
