To get sound out of your computer, you need to install a sound card.
Most computers come with some fairly good ones as factory basic. Likewise, if you have bought a machine for business use, you will be happy with something cheap and cheerful.
However, if you want to turn your computer into a home theatre or music studio, you are going to have to upgrade it.
One of the issues that is fairly crucial is whether your computer will support the sound card you buy. All will come with their own software, but this is no guarantee that it will work with your system.
Operating systems like Windows are pitched for the known brands of sound cards and may go a bit crazy if dealing with something unknown. Known brands are big names like Creative Labs, Diamond, Platinum, or AOpen.
Heavy heavy monster sound
Basically you get what you pay for with a sound card, so the more expensive it is, the better it will operate.
Generally most sound experts recommend SoundBlaster cards for those people with low-end computers, and things like the Diamond Monster Sound MX400 for those who have a Pentium 3 or higher.
Bits and pieces
When looking to buy a sound card, the only thing you need to look for is the number of bits per second it can process. This is the total amount of information the sound card can send to the speaker at once. The more information means higher quality and better sound.
Most sound cards that come with a shop computer system are 16 bits. However, the more expensive cards can reach more than 200 bits. Basically, now it's a matter of choosing a card in much the same way as a stereo. Decide how much quality you want and pay for it. Not really that difficult.
