I have got a studio quality USB microphone "Snowball" but when I try to record my voice using the applet it records silence. I tested the microphone in Audacity - it works (though I need to adjust the sample rate) and my java seems to be good: java version "1.6.0_03".
What might be wrong?

might be related to selecting an incorrect TargetDataLine in java program ?

I think the applet works fine, it just uses the wrong TargetDataLine. One way to solve this problem is to add a combo-box to allow user to choose the capture device. But this might be tricky.
