A USB camera with audio is 2 separate devices - the USB camera and a USB<br>
microphone - effectively attached via a hub internal to the camera case.<br>
<br>
Each needs to be initialised separately and microphone issues are<br>
completely separate to the camera driver as it doesn't attempt to touch<br>
audio devices.<br>
<br>
Is HAL showing 2 devices when you plug the camera in?<br>
<br>
Is your Linux audio/hardware manager attempting to initialise the<br>
microphone?<br>
