How to turn off motherboard's in-built sound card

[hut49]

I have successfully installed a whizz-bang sound card onto a Dell PC/Win XP Prof system but the motherboard's in built sound card is over-riding it. Device manager shows the new sound card is fully functional and no conflicts - any ideas how to isolate this or turn it off?

Should be through the BIOS, there should be a disable setting for On Board Audio.

errr..how do I get into the BIOS and change that?

On a DELL, press F2 when the BIOS screen appears (the one before the Windows XP boot screen). This will let you into the BIOS configuration where one of the pages will allows you to disable the on board sound card. Then Save and Exit, machine will reboot and to all intents and purposes, the built-in sound card will not exist.

Just been through this with a new PC but in reverse. I couldn't find anything in the BIOS or the mobo manual on how to enable/disable the integrated audio sub-system. In the end it turned out to be a little bit of ignorance on my part.

If the machine is "recent" you may find that option is disguised under the banner of "Azhelia" super-I/O.

Thanks - tried F2ing it a couple of times as the Dell logo comes up but just get thrown into the Windows advanced start up options / select safe mode etc after the Dell logo goes away. Any further ideas on how to get into the BIOS?

Depends on what BIOS its running.

Try pressing the 'delete' key instead of F2 - that's quite a common one.

That's it - the Delete key did it. Many thanks everyone!
