I have a AMD XP+ 2600 with Creative Labs Audigy LS. I am running the sound through the S/DIF output into my receiver. Whenever I start a movie and the very first audio appears (like the Columbia TriStar Intro) I get a loud Audio Pop. The rest of the movie is fine, and when I pause and restart there are still no problems. Anyone experience this and have any ideas on how to fix this? As a short term solution I turn my reciever on after the movie starts, but this is annoying.
