Perdida de sonido en Ubuntu 6.06

[Tomas Aparicio]

Buenas, gracias por el interes.

Intento responderos a todos:

No existe /proc/asound

Cuando hago sudo lsmod no aparece ningún modulo relacionado con sonido

La salida de lspci es

Arrancando con el kernel anterior si que existe /proc/asound y aparece la
tarjeta en lspci. /etc/modules tiene el mismo
contenido y no parece que haga referencia a nada relacionado con el sonido.
Lo mas interesante es la
salida de lsmod |grep snd

Efectivamente la tarjeta es una VIA 8235

Volviendo al kernel nuevo (2.6.15-26-k7) veo que hay un montón de módulos en
/lib/modules/2.6.15-26-k7/ relativos al sonido,
pero no el que me interesa (snd_via82xx, que si está en
/lib/modules/2.6.15-25-k7/).

Parece que está intentando cargar los drivers que no són, ¿no? ¿Por que no
están los drivers en el nuevo kernel? ¿Como los pongo?


También he notado que al arrancar ya no aparece el simbolo de Ubuntu con el
progreso del arranque. No se porqué
la actualización me ha hecho estas cosas, parece que a mi solo.

¿Alguna idea?
