I dont detect microphone

Hello,

I have a problem with the microphone, what happens is that the integrated detects it but have to talk pragmatically glued to the keyboard, it has good reception.

On the other hand the external microphone does not detect it then I hit him the model of my sound card.

I hope I can help.
