The Compaq Presario 5003US does not appear to have jumpers for
disabling the on-board sound chipset. Instead, you'll want to disable
the sound in the BIOS setup. According to the documentation I found,
you can get to the CMOS setup utility by pushing F10 while the system
boots (though on many other Compaq models, the F1 key does the trick).
To locate this information, I went to Compaq's website and searched
their support section. The pages you're looking for are:
Documentation, Manuals, & Troubleshooting Guides
Presario 5003US Desktops with any operating system
Maintenance & Service Guide Presario 5BW Series
(This page includes a link to an Adobe Acrobat PDF file for the
service guide for the 5000 series, including the 5003US model. The
PDF file includes a section on 'Jumper and Switch Information', but
none of the system board internal connectors listed are for disabling
Interestingly, there's another page on Compaq's website for the 5003US
which describes replacing a PCI sound card in the system:
Since your model has on-board sound, this guide probably does not
apply; moreover the PDF linked on this page does not mention any
jumpers or BIOS settings.
It's fairly common for newer PC's to have the ability to turn off
on-board equipment (like network cards or sound cards) directly in the
BIOS, without resorting to jumpers, so you'll want to run the setup
utility and look for a device section or options for disabling

Thanks for your efforts but none of the suggestions work. Indeed, the
BIOS is accessed via F10 but all it lists is an interrupt for the
onboard sound card, in this case it is an ESS Allegro card, most
Creative Technologies that makes SoundBlaster Live 5.1, said to remove
junmper on motherboard. However, right now Ill take any solution and
nothing seems to work.

After a little more hunting I've found that in contrast to the
official documentation on Compaq's website, this website,
http://www.igs.net/~ndaines/Qfiles/bmw-r.html indicates motherboard
jumpers for the ESS Allegro!
The settings are listed as JP6-JP8. When the first two pins are
jumpered, the onboard sound is enabled; when the second and third are
jumpered, the sound is disabled.
(Note that you may have to examine your motherboard a bit to find the
jumpers, as your motherboard may not exactly match their posted
When searching, this page was the last hit that appeared when I
searched with the terms Compaq, BIOS, and 5003US:
Hope this helps,
