I've got a problem recording, using my amp (Peavy Vypyr 30), and it's a recent one.

Everything on the amp works fine, so does the guitar. The computer speakers also work fine. So here is my problem.

When I load up Reaper, or Audacity, and start recording my guitar, the first 5 seconds or so record perfect, good sound quality etc. Then after that, the sound drops off dramatically and it seems to oscillate at a really poor quality. This happens every time now.

I've tried narrowing it down, and like I mentioned the amp seems to work fine, as I've recorded many things before. My guitar also works fine. I changed my computers though, got it professionally formatted. So I have a clean install of windows with drives. But now my recording does not work.

Any ideas on how to fix this?
