I recently built a new computer with an e-7050/610i motherboard.  It is working fine, except that I cannot get audio from either the line in jack or the microphone in jack to play through the speakers.  I have experimented with the HD Audio Manager that came on the motherboard driver disk, and no matter what I do the record side sliders are greyed out. 
 
I have tested with a known-good microphone and a known good line cable from my radio, and what goes in just doesn't come out.  I am not using the case-mounted jacks - this is with the jacks on the motherboard.  The jacks recognize when a cable is plugged in to them, so I know I am plugging into the right ones.   I can play the 3d demo and the speaker test just fine, so I assume that the D-to-A side of the sound system is OK
 
I went to the Realtek web site thinking to download the latest driver, but when I got there they warn not to use their driver, instead to download from the motherboard manufacturer, because the software is customized for each motherboard.  Meanwhile, EVGA encourages you to use Realtek's driver.  What to do?
 
Also, is there documentation for the Realtek HD Audio Manager software anywhere?
 
Thanks for any advice.

    does sound recorder work ok?  
     
    record something with the mic, into sound recorder then play it back and see if it works.
     
    Normally, you wouldnt want the mic to play back through the speakers as you would create feedback.
     
    for line in, try mucking about with the windows mixer and change the recording source and see if that helps.
    there should be a little utility floating around that tells you whats plugged in.
     
    use the realtech drivers

    +1 use the latest realtek drivers.   Hopefully that will get it fixed for ya, if it is a software/driver issue. 
     
    If the problem is in the hardware, you could set up a RMA, or there is always the option to pick up a $10-20 sound card, for basic use, or a nice one if your an audiophile, which would blow the onboard sound out of the water.
