ActionScript USB microphone stutter

I have a problem with USB mic input. When using my laptops internal microphone the following recorded buffer plays back just fine:

microphone = Microphone.getMicrophone();
microphone.codec = SoundCodec.SPEEX;
microphone.setLoopBack(false);
microphone.rate = 16;
microphone.addEventListener(SampleDataEvent.SAMPLE_DATA, processMicData);

private function gotMicData(micData:SampleDataEvent):void {
   micBuffer.writeBytes(micData.data);
}

But when I select the USB mic the sound stutters, like it's adding silence between the buffers. By the way, if I use a program like Audacity to record the USB microphone, everything works fine.

I would recommend trying to use the Microphone.setSilenceLevel() method. It allows you to set a level of microphone activity necessary for flash to read the audio input. Then, when no input is recorded, it won't write in silence when no information is received.
