What sound card port replaces all the various connections used for surround sound speakers?
  1. HDMI
  2. DVI
  3. USB
  4. S/PDIF
Explanation
Answer: D - S/PDIF is one port used for surround sound speakers and replaces older technology that uses multiple ports for a speaker system.

Sony/Phillips Digital Interface Format (S/PDIF) requires just one connection for an entire speaker system. This port consolidates several connections into one place on the sound card to reduce space requirements.
