Ok, so what application already has the audio port? Are you running an
audio or video player? Have you been using a web browser that was seeing a
video or just hit a page with video adds?

To put it another way, does this problem show up right after a fresh
login? or only after having used the system for a while. What does your
desktop use for most of it's non-jack audio output?
