Al hacer una instalación fresca de Ubuntu 8.04, el sistema usualmente detectará y configurará tu tarjeta de sonido sin que tengas que hacer ningún esfuerzo. Esto es correcto incluso con las tarjetas de sonido 5.1, siempre y cuando reproduzcas un archivo de audio o video que soporte este formato de sonido. Sin embargo, la mayoría de formatos de audio (incluyendo mp3) solamente soportan sonido en estéreo, por lo que solamente dos de tus parlantes funcionarán y los demás permanecerán mudos.
Tradicionalmente, los sistemas GNU/Linux como Ubuntu no traen una forma sencilla de decirle al sistema que todo el sonido sea reproducido en todos los parlantes, pero con la inclusión por defecto de PulseAudio dentro de Ubuntu 8.04 es posible ahorrarnos muchos pasos para lograr una configuración correcta de sonido.
PulseAudio es un servidor de sonido diseñado para funcionar en sistemas en red que se encarga de realizar la mezcla por sofware. Funciona en conjunto con ALSA, que es la arquitectura estándar de sonido en Linux.
Ubuntu incluye PulseAudio por defecto en su instalación a partir de Hardy Heron, aunque es muy difícil notar la diferencia debido a que no se incluyeron los programas utilizados para su configuración. Afortunadamente, no necesitaremos ninguno de ellos para configurar nuestro sistema de sonido y la mayoría de aplicaciones incluidas con el sistema ya han vienen preparadas para funcionar con PulseAudio.
Para poder activar la salida de sonido en los seis parlantes, en lugar de sólo los dos principales, es necesario ingresar el siguiente comando en la consola
Código :
sudo gedit /etc/pulse/daemon.conf
con el cual abriremos un editor de texto con la preferencias de PulseAudio. Luego casi al final del archivo cambiamos
Código :
;default-sample-channels = 2
por
Código :
default-sample-channels = 6
o en el caso de sonido 2.1
Código :
default-sample-channels = 3
El punto y coma al inicio de la línea sirve para comentar, y al estar presente el sistema ignora la instrucción, así que no debemos olvidar quitarlo. El número es el equivalente a la cantidad de parlantes del sistema; 2 equivale a un sistema estéreo ordinario, 3 a un sistema de sonido 2.1 y 6 a un sistema de sonido 5.1.
Luego de eso, solamente es necesario reiniciar el daemon de PulseAudio, para esto se debe introducir el siguiente comando en consola:
Código :
sudo /etc/init.d/pulseaudio restart
Sin embargo, por alguna razón esto parece no funcionar correctamente, así que es mejor reiniciar la máquina para ver los cambios. Luego, todo el sonido sera desviado hacia los seis parlantes.
En algunos casos puede que solo suenen los dos parlantes principales para alguna aplicación adicional que no venga instalada por defecto. Esto puede ser porque ésta viene configurada para trabajar con Alsa directamente y no con PulseAudio, para resolverlo hay que buscar en las preferencias de la aplicación y seleccionar PulseAudio como sistema de sonido.

Por Odin el 25 de Junio de 2008
No debería ser necesario configurar nada más para que funcione. Si se trata de una actualización de Ubuntu 7.10 a Ubuntu 8.04 puede que la configuración residual del sistema este interfiriendo con el funcionamiento de la tarjeta, se recomienda una instalacion limpia para evitar ese tipo de problemas. Como mencionaron más arriba, con este método es completamente innecesario (y poco recomendado) editar el archivo .asoundrc, así que si tienen este archivo de una configuración pasada es mejor borrarlo.

al grano. me ha sido terriblemente útil tu consejo. yo tengo ubuntu hardy con una audigy SE y me funcionó gracias a tus instrucciones en combinación con las descritas aquí, que tienen que ver con otro fichero de configuración .asoundrc . la cuestión es que poner por defecto 6 canales sólo me sirvió para corromper la reproducción de streaming del DVD (pixelotes verdes y eso). si no especificamos además la capacidad 5.1 en ese otro fichero es posible que no baste.
las otras instrucciones aquí: http://dudas.wordpress.com/2007/03/24/ubuntu-facil-sonido-51-en-ubuntu/

mi preguntas es.
tengo una lap hp pavilion dv6990la y compre un sorraund ligitech x-530 y trae las tres entradas correspondientes la cosa es que la lap tiene las tres entradas pero dos son de audifonos y la tercera es de micro la cosa es que estoy casi seguro de que no es 5.1 o por lo menos compatible de esta forma por que tiene el receptor de infrarrojos de spdif que es una calidad mas alta.
alguien puede ayudarme u orientarme para poder conectar estos tres cables y que se escuche como debe de ser .
de antemano les agradesco.

$ sudo /etc/init.d/pulseaudio restart
ha sido insuficiente. Aqui el asunto radica en no jugar demasiado con los controles antes de seguir los pasos arriba descritos para un correcto funcionamiento.

tengo un subwoofer de 5 parlantes y el bajo, logré configurarlo en windows pero de una manera muy poco ortodoxa, mi computador tiene una salida de sonido y dos entradas, en windows logró un amigo configurarlo para que las dos entradas se convirtieran en salida de sonido, y creo que es lo único que necesito para lograr el sonido del subwoofer en ubuntu, configurar esas dos entradas como sonido, ya que he probado todos y cada uno de los tutoriales que sugieren como arreglarlo y no ha funcionado... dejo mi mail en el caso que sepas como ayudarme a solucionarlo...
de antemano muchas gracias.

Código :
;default-sample-channels = 2
cambiar por (borrando el punto y la coma)
Código :
default-sample-channels = 2.1
Y listo funciona perfectamente después de reiniciar. Supongo que lo mismo para 5.1, simplemente escriben 5.1.
