HP Pavilion dv6-6030ew microphone doesn't work

Hello,

For first I'm not from US, so sory if I don't use english right.
Like in topic, I have problem with my microphone in laptop,  after I reinstaled windows (windows 7 x64) it stops work, nobody can hear me on skype etc. Windows show me I have Updated audio driver (IDT v 6.10.6345.0) I also dowlnoad some more Updates from automatic HP support.

Thanks for any answers.
