    Help! A lot of problems with microphone config - ATI Technologies Inc SB450 HDA Audio

    Hi,
    I've recently switched to Kubuntu (gutsy 7.10), and I am having serious issues with my microphone... the sound works fine, headphones too, but I am trying to use a headset with a microphone, and i can't get the microphone to work... I think there must be a conflict with something else, because everytime i try to test it, either with Ekiga, Audacity or Skype, the application just freezes.
    Help, i don't know what to do, and i really need to use an Internet telephone application in order to talk home... if anyone knows what could be wrong, here are my card specifications
