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?

    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

    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.

    DIP switch.

    My machine allows me to do it via the BIOS.
    ....because I have MP3 mixing software that requires two separate output
    better SB card.

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

    Disable the AC'97 and buy another SB card.

    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.

    CJ came up with this:

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

    Go to control panel\sounds\audio, there is only one device you can select as
    default. Whether both will output or not I'm not sure but make sure both
    drivers are loaded properly to test.

    Really? Is there documentation from MS stating this?

    I seriously doubt this too. Why would they write reputed software (Traktor)
    if the operating system doesn't support an absolutely *key* feature of it?

    Have you got experience of two SB cards in the one machine?

    I did this and it made no difference.

    I think what he was saying is that XP's built in sound only supports
    recording or playback from one source. I couldn't imagine that the
    operating system would only recognize one or the other sound devices. That
    would be a real bummer for those that want to work with digital studio
    stuff like i used to before buying a 16 track digital recorder.

    Yes but not in XP and not for a coupe years since I bought a 16 track
    digital recorder.

    This intrigued me John, because in the past I have used two sound cards
    in the one computer, so I knew that it was possible. I wasn't sure
    though whether you would be able to use them in the way you wanted. As
    far as I know it was not possible to have them both playing the
    identical filetype - ie both playing wave or mp3, but it was possible to
    have one for midi and one for other sounds.

    The mixing side of it is not my forte so I downloaded the demo version
    of Traktor DJ Studio 2 - is that the one you have?

    In the readme file it has this to say:

    If you have a multi channel sound card, assign the master channels of
    Traktor to the outputs of your sound card connected to the amplifier.
    Connect the monitor (headphone) channels of Traktor to the headphone
    outputs of your sound card. In OSX you can use an additional stereo
    soundcard for the master output and use the in-built soundcard for
    monitoring by using Core Audio drivers. The Windows version does not
    support two separate soundcards.
    In many multi channel sound cards the headphone outputs are identical to
    outputs 1 and 2. In this case the master channels of Traktor have to be
    assigned to the outputs 3 and 4 of the sound card and these connected to
    the amplifier.

    It looks like you may be out of luck as it does specifically say that
    the Windows version does not support seperate cards, so your only
    alternative may be one of the packages they advertise on their webpage,
    or fork out what I would imagine to be big bucks for one of the
    multichannel soundcards or external USB sound systems.

    Ahhh.... thanks for that. Oh well I'll look into a multichannel sound card.

    You must turn off the onboard sound in setup when you use a PCI sound card.
