I recently bought a headset. The speakers are working fine but when i tried to test the mic using sound recorder on Windows XP ...the mic doesn't seem to work. I tried the same on my friends PC but the mic worked fine there. Another notable issue was that the sliding bar of the sound recorder didn't move forward when i pressed the record button. Also when i tried the sound recorder on LINUX (gnome-sound-rec) it crashed. I suspect there is some hardware problem. Any suggestions?? how to solve or detect the problem? I have an Intel D845GLVA motherboard, no additional sound cards.
