Dica:
como configurar som Ubuntu Surround 5.1 CMI8738, placa genius
tive uma certa dificuldade com essa placa de som CMI8738, 5.1 6ch da genius.

estava com o problema,
a cada musica ou video o audio desconfigurava,
dai tinha que clicar nas opções de audio
e trocar a opcao de 5.1 para 5.0
e clicar novamente na 5.1 que voltava a tocar as 6 caixas.
muito chato.

ja estava quase compilando o kernel com dicas encontradas ne web.
e achei varias dicas. que resumi todas abaixo.
