A USB camera with audio is 2 separate devices - the USB camera and a USB microphone - effectively attached via a hub internal to the camera case.
Each needs to be initialised separately and microphone issues are completely separate to the camera driver as it doesn't attempt to touch audio devices. Is HAL showing 2 devices when you plug the camera in? Is your Linux audio/hardware manager attempting to initialise the microphone? On Fri, 19 Jun 2009, Arlindo F.
