Hello All,

I have a tone that is going out through some speakers.  However, even 
with the microphone unplugged, that tone is getting injected into my 
video file.  I want to complete filter this tone out since it is 
completely out of sync with the video.  Can someone point me to some 
documentation of how to do this in C code or maybe even some examples?
