Here is the final part of the lession:
Screen size: if you want to get the best atmosphere, make sure that your screen is at least 19", a 21" would be even better. Also, do not scimp on cables and connectors. Most people who put together a Surround Sound system and incorporate it with their computer get fuzzy background noise. Most of this noise can be eliminated with proper shielding and the right kind of cables. I use monster Cables and they work out great. Also, you don't want to buy cheap components, mianly your reciever and speakers. If to much power goes through them, it will cause damage and lower the systems life.
The above Digital output cables from Hoontech and Creative are if you want to do digital sound editing as well. If you don't see yourself as using digital input (say, if you want to record from a CD Changer or Minidisk) Don't spend money on it. Creative also makes an adapter to hook up the digital output that you see on the back of your card and can be found <A HREF="http://www.soundblaster.com/accessories/cables/" target="_new">here</A>. This is a toshlink/minilink converter and only costs $13.00.
The Soundblaster Live 5.1 boards are for decoding to non-digital environments, like a set of analog computer speakers. If you buy a Digital reciever, it will do the decoding for you, and therefore, you will not need those features. Make sure that if you wanted to watch DVD's that you DVD software or hardware decoder allows digital out. Although I currently do not use digital out for my computer's sound, I do have the ATI AIW Radeon and it provides Digital otput, for DVD movies only. If you plan on watching TV on your computer, I would Highly recommend this board for its features and, once loaded and setup successfully, stability. If you don't have the money for a full blown system of this magnitude, I would suggest buying in steps. Start by getting the receiver and stereo speakers, then as time goes on, add more. This not only allows you to get good quality parts, but it saves your checking account of large outflows all at once. If you have anymore questions, let me know.
If it works for you then don't fix it.
