opensuse 11 picrophone problems

hi all,
I’m new to linux. Today I’ve installed opensuse 11 (before I have opensuse 10.3). I’m using notebook dell inspirion 1520 - it has one mic that is build in the notebook and standart line in chanel. On windows everything is ok. On my old opensuse 10.3 after tens of hours of work I finally get to work build in mic (standart line in still doesn’t work under 10.3). Now after my upgrade to opensuse 11 there is nothing to work again .

Please help!
