Has anyone gotten an external microphone to work with the T904? I have an external microphone on a long cord that I want to use to record interviews with people. When I plug an external microphone (or a headset with a microphone) into the Headphones port, the computer still uses the internal microphones and does not use the external microphone. The Headphones port seems to work fine for external speakers. This is harder to test than you might think because the internal microphones are very sensitive. You can talk into the external microphone and the internal microphones still pick it up. I installed the latest audio driver from Fujitsu and have spent a lot of time trying to get this to work. Any suggestions appreciated. It would help just to know that someone else is certain that they got an external microphone to work.
