It is something someone else added to the code to make the detection 
criteria in relaxed mode even more relaxed. If setting that helps, 
something in your channel must be causing some serious filtering of low 
frequencies. Can you try logging the audio to a file, and send it to me 
for analysis? chan_spy, or something like that, should do the job.
