Ubuntu 10.10 sem som em Mac 7.1 Resovido

[Ed Sant]

Instalei dia 22 o Ubuntu 10.10 em meu Mac 7.1 e desde entao venho lutando para ouvir algo, e nada funciona.
Os graficos de saida indicam que o som esta saindo normal , que o mic esta gravando normal, mas nos falantes e no fone de ouvido, nada acontece.

Ja reinstalei umas 10 vezes , testando todas as dicas possiveis e nada funcionou.
Agradeco a ajuda.



Resolvido como segue:


No terminal digitar:


   gksudo gedit /etc/modprobe.d/alsa-base.conf


No final do arquivo acrescentar a linha:


   options snd-hda-intel model=mbp89


Salvar e reinicializar .



Som totalmente funcional.....
