Olá, boa tarde!

sou iniciante no linux, e estou tendo problemas para fazer funcionar o som na minha maquina. A situação é a seguinte: tentei instalar o pacote de hardware do site www.realtek.com.tw, instalei o aplicativo (que acredito eu ser o alsa), mas por algum motivo, depois de eu fazer isso o programa "alsamixer" não está mais funcionando, reportando o erro: "cannot open mixer: No such file or directory". Percebi também que no icone de som->dispositivo de saída. Está "dummy output". Alguém, por favor, sabe como resolver essa encrenca? Meu linux é o Linux Mint 14(Nadia), cinnamon, baseado no ubuntu. Segue configuração do lspci:
