my sister has a inspiron 1100 for school. It runs with xp and from what I have found a sigmatel sound card stac97 sys. Now I know nothing of laptops and little about computers, learning every day. I plugged in a old set of speakers and they wont work, have tested them, tested the headphone jack and spent a day navigating around to find the problem. if this is an intergrated sound card am I limited to what speakers I can use? or is there something  else I should be doing, it says everything is running fine.

This all comes down to she wants speakers for christmas and when I type her service info into dell, they list only one pair of speakers that I can buy. Is this my problem?  I can't beleive ther's only one pair of speakers that will work with this computer.                            thanks for helping me learn   cjs
