I'm kind of late on this, and you may already know this, but anyway:

Windows 7 can be a royal pain in how it handles sound devices.      Type:

manage audio devices

in the windows search box.

Depending on what you are trying to do, go to either the recording or 
playback tab.   Under each one, you will find a list of devices on the 
pc.  Arrow down the list and you will  see that anything that has 
something plugged in will say "ready" and  if nothing is plugged in, it 
will say "not plugged in".

After you select a device, tab down a few times and you can change 
things like levels.

One device is going to be labled "default".   Perhaps the software you 
are using is set to only use the default device.  You may be able to go 
into the software and tell it  which device to use.  Be sure something 
is plugged into that device so it will be recognized.  You can also 
change  the default device in Windows audio devices, but think this 
through first, since  it may have unintended  results on  other software.

If this is no help to you, chalk it up to an  early morning.
