user16864: I am new to Arduino and I want to connect it to my 2.1 speakers and later to a 5.1 surround system.
The purpose is to play some wav sounds when a button is clicked or when a trip laser is cut. What should I do in order to play those wav around through the speakers? I also have an SD shield.

user13432: First, you need to figure out the bandwidth requirements and if this is possible at all. You need to do some basic calculations and answer the question if the Arduino and the different components have the bandwidth (byte/second) that is required.
The Arduino MCU (AVR) is too "weak" to do this on it's own. A special shield is required. Such as https://www.adafruit.com/products/1788
The Arduino Due has more processing power but still not stereo quality; https://www.arduino.cc/en/Tutorial/SimpleAudioPlayer
More info to be googled.
Cheers!
