I've done some dtracing and noticed the static/scratchy sound appeared
immediately after pidgin played a sound (for someone logging in).
Pidgin uses these two devices to play a sound:
/dev/mixer
/dev/sound/audiohd:0dsp
Next, I'll keep pidgin muted for a few days and see if the problem
still persists.
These apps also do audio but they use these devices:
/dev/audio
/dev/audioctl
firefbox-bin (opens many times, perhaps upon each web page
visit that contains flash?)
Xorg for bells in terminal windows? Opens many times.
mixer_applet2 Opened once at Gnome startup.
