B.
Document Management Server is used.

C.
The correct version of a codec is not installed.

D.
The Document Inspector is used.

E.
The sound card is not installed in a computer.

Explanation:
A sound card is an audio expansion card, which is used to facilitate input or output of the audio
signals to and from the computer. A user can play the sound clips by using a sound card.
Answer option A is incorrect. The sound clips will not be affected by the use of a digital signature.
Answer option B is incorrect. The sound clips will not be affected by the use of Document
Management Server.
Answer option D is incorrect. The sound clips will not be affected by the use of the Document
Inspector. The Document Inspector is a powerful feature of PowerPoint 2007, and it is not available
in PowerPoint 2010. It is used to inspect a document for comments and annotations, document
properties and personal information, custom XML data, invisible on-slide content, off slide content,
presentation notes, etc.
Answer option C is incorrect. A codec is used to re-encode a file. The sound files need a codec to play
its sound correctly. If the correct version of the codec is not installed, a user will not be able to play it.
