Well, I have done some close investigation and found that the log
entries for the Audio Input Status Changes is not as critical as I
thought. By listening to the logged events there are many instances
where there is no audible "hit". At times there will be an audible
drop or pop, but now I find they are not all being passed through the
system. I have some other tests I am going to do, one of which
involves moving the broadcast delay out of the studio. Then we will
see how things react "on air".
Still wondering if others have had this issue.
