Microfon problems s400 with noise reduction

Question

Hello people,
have a problem with the microfon sound.
This recording is either noisy (without HD driver and with HD drivers without noise reduction) or it is distorted (with HD drivers and noise reduction).
Drivers I've tried from the Lenovo page and also from Realtek already.
here are a few tests
Noise: https://dl.dropbox.com/u/1182020/test% 20HD% 20with% 20the%% 20treiber 20nachhallred.wma
distortion: https://dl.dropbox.com/u/1182020/test% 20with% 20HD% 20treiber% 20with% 20rauschunterdr% C3% BCckung.wma
in the device manager for microphone stands for the version: 6.2.9200.16384 Microsoft.
Use Windows 8 Pro which I installed by myself.
Would be grateful for suggestions, I can not skype otherwise.
greeting

Dark areas have less bits to encode their values so a single bit of noise is a higher proportion of the total value.
For the basis of the default processing, to match the human eye’s response to dark and light, darker areas are brightened more than bright areas, using a non-linear gamma curve.  This magnifies the noise in darker areas.
If you boost the brightness of dark areas using Shadows or Clarity, you are making that noise even more visible.   Think of brightening as digitally increasing the ISO. 
Adobe’s noise-reduction is calibrated to the original photo’s ISO setting, not how much you have digitally increased the ISO by brightening it, so if you have magnified the noise by extreme processing, you may be beyond what maxing out the NR sliders are calibrated to remove.
Exporting sharpening will sharpen any remaining noise.
Are you using the Mask slider in sharpen to keep from sharpening the noise grain in the Detail section?  Use the Alt key while moving the mask slider to determine the optimal Mask level for a particular photo, where you can’t to have the edges indicated but not the wide areas of little detail.
It’s hard to guess what you’re seeing without seeing a screenshot.
