I'm unable to use my Logitech microphone headset at all. I have Realtek sound drivers and windows says it's updated to the latest already, i've also played around with the settings abit too, increasing boost levels, etc. etc. the headset i'm able to use for windows xp though! not windows 7. when i go to the sound options, it detects the microphone put in, it just doesnt pick up sound at all. i bought the computer with windows 7 just recently. thanks!
