I don't know if this is a PC related issue or one with my UX1, but I'm getting this very odd kind of crackling hiss/white noise when I'm using the UX1. Here's an audio clip of the problem,

To help rule out various other factors, I tried using the UX1 with both Reaper and Riffworks and get this same kind of white noise/crackling hiss as the note/chord fades. I tried using different guitars, different guitar/usb cables, real/sim pedals, and every amp sim I've got archived. I've also tried standing well away from my PC while recording, as well as taking the PC to 3 other rooms in my house, but to no avail. Keep getting this noise no matter what and where I do it. That said, I like to rule out the UX1 as the culprit before I take my PC in to the shop to get it looked at.
Also, if it's of any help, I'm running Win 7 64 bit, and my drivers, both PC and Line 6, are up to date.
Any input would be extremely welcomed at this point.
Thanks.
