Otro Ubuntu sin sonido (solucionado)

Bueno, como muchos otros que vi en el foro, tampoco tengo sonido. Tengo Ubuntu 7.04, ya le subi los volumenes al alsamixer y le saque todos los mutes. Segun el alsamixer mi tarjeta de sonido es HDA NVidia y el Chip, Realtek ALC 861-VD. Les adjunto aqui mi lspci:

la version del alsa-base que tengo es la 1.0.13-3ubuntu1 que viene ya con Ubuntu, y ya probé agregandole a /etc/modprobe.d/alsa-base esta linea que se sugeria en algun lugar del foro: options snd-hda-intel position_fix=1 model=3stack y no pasa nada. Que mas puedo probar?

Gracias
