First of all many compliments to the author... very clean way of writing components...that work too

I got a problem in live audio.. capturing audio from a video cam microphone. In few words everything works fine with a microphone separated from the cam... but when i try to use the micro integrated with the cam... th system seems to work for a while... then, suddenly, the audio is corrupteda nd volume gose 100%. The streams are right.... it seems that the audio from the cam came corrupted....
Any idea how to solve the problem?
many thanks
