Im having problems with my mic, just recently I have tried to run the voice test in sound,but all I hear when i try to hear my voice being played back to me by my PC is crackling and hissing, I use or used to use Yahoo messenger voice chat quite often untill this error, when i enter a chatroom now i dont see anyone else being indicated as using voice chat. i tried the normal browser version of yahoo and i can hear quite clearly other people but they cant hear me,just the hissing and crackling, i had to fdisk and reformat a while ago,and someone said i may have a conflict with my sound card not recognising my voice, but hardware management says no conflicts!? is it likely i need a new mic? sound card or both ?
