Ubuntu 12.04 parou de reconhecer placa de áudio

[dbrand]

Olá, pessoal! Paz para todos!

Quero pedir a ajuda de vocês, pois meu Ubuntu parou de reconhecer a placa de áudio, sendo que, nas configurações aparece só uma saída fictícia. Já reiniciei várias vezes, no entanto, sei que o problema não é de hardware, pois pelo live CD funciona perfeitamente o som.

Detalhe: isso aconteceu depois de eu tentar criar uma máquina virtual sem sucesso para rodar Windows 8 consumer preview.

Obrigado! Aguardo respostas. Deus abençoe a todos!
