problemas com o microfone

[hishin]

Bom dia a todos.

Pessoal, estou tendo um problema com o meu mic, só falta ele pra funcionar tudo e antes estava funcionando normalmente, simplesmente parou. Não sei se foi algo que eu desinstalei ou mexi q fez isso.

Meu ubuntu é o 10.04 amd64. Meu note é um dell inspiron 1525. Segue meu lspci:
