hola como estan, no hace mucho tiempo acabo de instalar Ubuntu 12.04 en mi laptop, pero tengo un pequeño inconveniente y es que no se puede escuchar ningun tipo de audio, por lo que intuyo que debe ser problemas de drivers, pero como soy nuevo no se que hacer, echenme una mano porfa.
info sobre mi controlador:
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
si necesitan algun otro dato mas con mucho gusto lo puedo dar,
Gracias.

RE: Problemas con el sonido de mi laptop
Hola,
Puedes dar el contenido del script alsa-info.sh ? Es una herramienta de diagnosis que da información sobre tu sistema hardware y software relacionado con el audio.
Para ello, abres una terminal y pegas el comando de abajo (Control+Mayus-V para pegar en la terminal). Cuando te pregunte, puedes salvar el resultado localmente (en tu ordenador) o bien subirlo a internet. Lo más facil es que elijas la segunda opción y pongas aquí el enlace. A ver si podemos ver algo.

Esta es la info que pude conseguir de mi ALSA

RE: Problemas con el sonido de mi laptop
Hola,
No estoy seguro si va a funcionar pero puedes probar lo siguiente:
Editas el archivo de configuraciçon de alsa, con este comando desde una terminal:
gksudo gedit /etc/modprobe.d/alsa-base.conf
Al final del todo, añade esta línea:
options snd-hda-intel model=auto
Guardas y cierras. Reinicias el ordenador. Abres una terminal y pones:
alsamixer
Compruebas que los niveles son correctos.
Otra cosa, ¿Qué modelo de laptop tienes?
Otros "modelos" con los que puedes probar en el archivo de configuración, son los que aparecen en la lista de abajo para el codec ALC269 (sustituyendo "auto" por alguno de éstos):
ALC269
======
basic
quanta
laptop-amic
laptop-dmic
fujitsu
lifebook
auto
