[ICOM] IC-2100 audio

[GGLL]

Take a look at:

> http://www.okokchina.com/Files/uppic/Electret%20Condenser%20Microphone755.jpg

you'll see, despite the terminals could be wire or pad for soldering, 
one terminal is connected to the AL case, but it is a mechanical contact 
and I've seen many failing due to poor contact.
Sometimes i've solved the problem pressing the case to the track with a 
needle or thin solid wire.
