Lack of sound

[aay]

If you have it, it will be in the pc BIOS.

What if I don't have one? Is there another way?

First it would help if you posted your make and model of sound card. If it's not supported in linux at all, then disabling your support in your bios isn't going to help. Once you do that I suggest googling on the card like this: "linux card_model". That should get you some basic info as to whether or not it's supported. Once you have some basic details like this come back and post them. Then people will be much more able to help you.
