Configuración de ALSA en Netbook HP Mini 1020la para solucionar el problema de Audio y Micrófono en Ubuntu 9.04 y UNR

Desde hace ya casi 4 semanas vengo intentando reparar el Audio de mi HP Mini 1020la sin ningún éxito.

Por esto decidí instalar la versión MIE de HP para el Netbook y comprobar si es posible que tanto el audio externo como interno además del micrófono funcionaran en Ubuntu.
Para mi sorpresa descubrí que todo funciona a la perfección, pero obviamente no tengo intensiones de quedarme con el MIE por mas bien que funcione.

Mi idea entonces es aplicar la configuración que trae el MIE para el Audio a Ubuntu 9.04 y UNR, pero el caso es que no soy un conocer de Linux a ese nivel. Por esto necesito ayuda de la comunidad para poder aplicar estos cambios y que juntos solucionemos este problema que tiene en vilo a tantas personas deseosas de usar Ubuntu 9.04.

Durante este post voy a colocar toda la información que pude o supe recopilar sobre los controladores de audio en la netbook además de algunos screenshots que tal vez puedan ser útiles para aquellos conocedores a fondo del tema en la meta de poder solucionar este inconveniente.

- Primero que todo voy a comenzar con la información que pude recopilar del sistema.

==================================

Bueno, espero que toda esta información sea suficiente para que podamos solucionar este problema, yo mismo instalare de nuevo Ubuntu 9.04 en mi netbook para ayudar activamente en la solución.

Gracias a todos los interesados por su ayuda.
