ok... i have a headset (koss cs-100) with mic that is not working for some unknown reasons. the headset itself is working nicely. i can hear sound and such, but the mic is not working. i have used it a lot of times before without issues, but now it does not work all of a sudden... you know when the mic is working and you 'tap' on the mic, you hear this mic kind of sound.. well, i cannot hear it anymore... the headset got of course 2 jacks; 1 for headset, 1 for mic. i have plugged the headset to the headphones-port and mic to the pink mic-port. when i go to control panel -> sound -> recording, i can see that the 'microphone - realtek high defenition audio' is enbaled and set as default. i still cannot hear that tap-sound.... i have also checked everywhere whether the mic is muted, but it's not! i've turned the volume to 100 and the levels to +10db. this is driving me crazy! i have a webcam with a mic, but its quality sucks, so i have disconnected the webcam. i wanna use the mic on skype, but apparently it does not work... :/ so, HOW on earth do i get my mic on my headset to work again?!?!
