Yuo should be bale to disable your integrated sound card in the BIOS and then install a new sound card.

You'll need to go here:

Click "Download" from the menu at the top of the page - Choose "laptops" then "satelite" then find your model #.
This shoud give you page where you can download the audio driver.

you shoud instoll proper drivers and DVD player softwar

well if your motherboard supports your speekers it shoud run corectlly, but if not, you shoud get a special sound card with cd, which will allow you to use your speakers. if you already have that sound card and installed drivers you should go to your sound card control pannel and make changes there to use all your sound system speakers.

C700 is not a model number but it is a model series. i.e. there are many different model numbers within the series called C700. You need to pick you EXACT model number from this page
and go to the Software and Driver section of the page that comes up, then pick the XP operating system to see what comes up.
If further help needed, come back with a more specific model number

first check additional speaker to your pc and check sound output
