Context: We have a problem with our Microsoft Messenger VideoCalls : We can not transmit sound along with the video . We are using a Logitech QuickCam Pro 5000 . We used to be able to send sound though , strangely , the sound only worked via a separate microphone plugged into the mic hole in the back of the pc rather than through the microphone built - in to the Logitech camera . We had the microphone plugged into when we installed the Logitech QuckCam with the built - in microphone .
Question: Why can the writer not access sound ?
Option 0: None of the above choices .
Option 1: They unplugged the external microphone .
Option 2: The camera does not come with a microphone .
Option 3: The computer did not come with a microphone .
Answer: 1
