I plugged it into my mic port on the front, the program pops up, asking what it is, I click on microphone. I try to record on sound recorder, it doesnt work, I try to talk on skype, it doesnt work. I try the multi port headphone port, I click microphone, still nothing. I try the microphone port on the back, still doesnt work. So I try on my windows 98 computer upstairs, it works. Problem is, I need internet so it has to work on my downstairs WindowsXP computer. It is obviously the computers fault. I did check the mic volume too, and it's all the way up. Any ideas on what I should do?? any help would be greatly appreciated.
