Problema com Som - HDA INTEL - REALTEK ALC662

[hayttle]

Olá pessoal, gostaria que me ajudasse em uma tarefa aqui no meu micro.

Instalei o Ubuntu 8.10, está tudo atualizado, porém o som da minha placa onboard, MB GIGABYTE GCM-S2C fica picotando/falhando, porém quando eu rodo o live cd do Ubuntu, fica normal, é alguma coisa de drive ou configuração que não estou conseguindo solucionar, já tentei de todos os jeitos, mudando as preferências de dispositivos de som e nada. além de não consegui colocar para funcionar o home teather em 5.1 canais.

Obrigado,
Hayttle


Segue a minha configuração:

Bom, descobri o problema da falha, de ficar picotando, é que os controles do volume estavam no máximo, quando eu diminui um pouco, o som ficou normal.

A questão agora é fazer funcionar em 5.1, pois só saem na frente em 2.0.

Sds,
