Apparently, in most cases the third wire is to provide DC to bias an
electret microphone. Doesn't ICOM do this too? I determined which
connection was involved on my SB-16 card, and made up a microphone plug
that used only the audio line and ground. Of course, there may be sound
cards with a stereo mic input, so as always YMMV.
