sony vaio: auriculars i microfon

El tema del headphones m'ha tornat boig però ho he lograt gràcies a ubuntu forums.

Hello,when I first installed ubuntu on my sony vaio vgn fz 21m I only had sound via the build in speakers.
The audio jack didn't work (I didn't test the mic, sorry)
so i searched the ubuntu forums.
what seemed to do the trick with my 7.10 was to go to the software sources under administration,
go to the update tab and to check the gutsy backports. update your repository list then run in a terminal:
sudo apt-get install linux-backports-modules-generic
(generic would be the normal case but it could also be i386 if you have been messing a bit around in your synaptic.)
linux spits some output and when it's done I used the following command:
sudo gedit /etc/modprobe.d/alsa-base
now a gedit file should open.
be carefull now. you are editing a file which only root has access to.
just add at the end of this file in a new line

options snd-hda-intel model=vaio

now reboot and cross your fingers

For the record this is just a cp from someone elses post

Fins aquí el tema dels auriculars.

Ara anem pel tema del micro.
És important haver aconseguit que se sentin les coses pels auriculars i no pels altaveus.
Ara el que he fet és anar a Aplicacions/So i Video/Grabar so
Hi ha una opció on seleciones el canal d'entrada. He escollit Internal Mic i també em funciona amb Captura.

Pel que fa a les propietats del volume les tinc totes activades a tope excetpe la pestanya que diu Commutadores , l'opció que diu Mic Jack, la tinc desceleccionada.
