D975XBX2 Audio Issue

    Just built a new system (Intel D975XBX2 and E6700, 2GB Kingston HyperX
    DDR2-800, Nvidia 8800GTS) running a clean install of WindowsXP MCE. The
    performance and stability is awesome.

    The only problem is that the Sigmatel audio chip is barely picking up
    sound from the mic, even though I turned on the MicBoost in the control
    panel. It's so weak that the Windows sound recorder applet barely picks
    up sound even when I'm practically yelling into the headset.

    The audio properties applet has 2 microphone inputs, one marked as
    'Microphone' one marked as 'Rear mic'. I am using the 'Rear mic'; I
    didn't even hook up the front header since this is an under the desk
    box and I didn't want wires stringing down the front. Of course I have
    the 'Rear mic' selected in the Recording Control applet and all other
    sound inputs are de-selcted.

    Thinking that it's a software thing, I have tried both sets of audio
    drivers from Intel (one with Intel sound applets and one with SigmaTel)
    but I get the same result. Interestingly, the Intel web site refers to
    the procedure for setting the RealTek sound device as the default
    input, even though this board only ships with SigmaTel.

    Has anyone else seen this issue or a solution for it?

    Thanks in advance.

    There is really no set standard of matching microphones to
    the microphone inputs in the consumer market. Connecting the
    microphone through an audio mixer could generate the proper
    input level for the real microphone inputs. This would be
    true for more of the professional electet and dynamic or
    condensor microphones.

    I have what sounds like an identical problem with a D975XBX board.
    Bummer. I've tried three mics; none work on either mic port on the
    D975XBX, but all work well on other computers. I've reinstalled drivers
    about a million times - nothing works. I'm about to give up and buy a
    cheap sound card.
