Mobo On-Board Sound + PCI Sound Card?

I have a motherboard (LX BN790E) with on-board sound (Avance AC97). I also
have a Creative Sound Blaster PCI card. I would like to make use of and have
both sound devices installed on my machine simultaneously.

My problem is that whenever my SB PCI card is installed Windows XP doesn't
recognise my on-board sound, yet when I remove my SB PCI card the mobo
on-board sound works fine.

Does anyone know how I can get both working at the same time and/or what the
problem is?

It's never easy to get a dual sound card setup in windows.try moving
the sound card to another slot.Windows was never designed to run more
than one sound system and even if you get both cards running you may
only be able to use one for certain functions and the other for the
other functions.
Also check the Device Manager using Safemode as per,

One isn't actually a "card"... it's built into the mobo.

Do you think it's worth moving the single PCI card?

other functions.

I need it for software which is designed to use two sound output devices.

Also check the Device Manager using Safemode as per,

The problem I have though is that XP doesn't even *detect* the mobo on-board
sound (i.e. no entry in device manager) when the PCI card is in... surely it
would have to have an entry in the device manager before I could adjust any
of the setting as specified in that link?

Why would you want to use an AC97 over a SB Live?

I want to use them simultaneously. I'd use the SB card as the primary
device.

Hi,

there is no problem. It's that on cheaper computer installations without a separate sound
card you just use the generally inferior but adequate on board sound. If you then purchase
a seperate higher quality sound card you turn off the on-board sound via a DIP switch. Why
do you want or need to run both together? Your system can only output sound to one audio
device at a time anyway so disable your on-bnoard sound and use your better SB card.

My machine allows me to do it via the BIOS.

....because I have MP3 mixing software that requires two separate output
devices.

This is the setting I had when I only required one sound device. I now need
two.

It's easier in Win9X/ME than in XP if the BIOS has the option to
disable ACPI.XP not only has ACPI enabled by default but also APIC.If
you can disable these options in your BIOS and then do a repair
install of XP you should then be able to manipulate the IRQs.This is a
very specialist area.I've had dual sound card setups running in
Win9X/ME but never tried with XP yet :/

The on-board sound uses one of the PCI slots internally and if you have the
SB plugged into the same slot (MB hardware dependent), both cannot work.
Try moving the SB card to another PCI slot. Un-install it first; shut down,
move the card, then turn the system on and re-install it.

XP is designed to use only ONE soundcard source; in your case you can use
EITHER the onboard or the Creative, not both.
