This seems to be a universal problem with Windows 7. I have 32 bit installed on both my laptop and desktop and on both the microphone level is too low despite enabling Boost Gain, tinkering endlessly with the sliders and options (such as CD Quality, enhancements, etc) and nothing seems to improve the level. On my laptop the sound uses High Definition Audio and my Desktop has a Creative XFi Extreme Music card. As previously mentioned, both have the same issue - the mic is way too quiet unless its right up against my mouth and I'm shouting. I've tried several different microphones. As far as I can tell this problem existed in some of the earlier builds of Windows 7 going back to the beta. Any more solutions? I've reached the last straw now and am really frustrated having wasted hours of my life trying to resolve the issue.
