Audio Features missing on my Computer

[Lazerlord]

I recently bought a passive microphone for recording videos with, and I hooked it up to my Lenovo Y500. I expected nice, clean sounding audio that has low noise, as all of the tests of the microphone that I've found online sound pretty good. I plug it in and find that about 1/8 of the waveform is comprised of almost pure static. It sounds like muffled white noise, and is not coming from background noise, but from electrical noise. Most micophones would sound like this without an option in realtek HD audio manager checked, that one being "noise supression". Every single computer I have ever used had that feature, and it worked faily well, however, on my Y500, that option is non-existent. Not in the audio manager, and not in the windows configuration either. I have downloaded and re-installed newer and older drivers, and I still havn't had any luck. If anyone else has had this problem, or has an idea of how to solve it, please let me know.

I had the same problem. Front panel input would let noise suppression work, but rear IO didn't.

But using noise suppression made my mic sound worse, so I invested in a cheap $30 sound card (asus xonar DG) and my mic works perfectly, no EMI/static, and no need for noise suppression.
