Recently I have get the new Lenovo ThinkPad X220, and I am thinking that this a excellent machine; but I am disappointed with this machine. And this is caused by the Conexant 20672 SmartAudio HD soundcard. This is not working in this system properly. And for getting resolve the problem I have also tried with driver update to 8.32.23 but after this also get the same problem. This card is not working properly when I am trying to use the programs such as Skype, the mainly limited mic settings either create a huge background hiss or a extremely silence mic, even when using a confidence external mic plugged straight into the card. Can anyone help here in this cause.
