K42Jc Notebook(ALC269) port switch between headset, headphone, mic

[Madura Anushanga]

Hi,

I want to switch between headphone, headset, mic input/output modes when I
plug in devices. Alsamixer shows two capture channels, one is for the
internal mic. I don't know how to use the other. I've tried switching some
things on and off in hda-analyzer but I failed to get the functionality that
I wanted. This notebook only has one audio port(TRS 3.5mm), so the selection
is vital if I'm going to use an external mic. Currently the port is acting
as an output only port. And something fishy goes on when I select "Analog
Stereo Input" in profiles in Sound Preferences. It lets me use the external
mic through the audio port but only if I push the jack half way, the input
is detected and I can record it(but there's no sound output after I select
this profile, its input only). I some how think that this is the "mic" mode
and if I can get it to work on "headset" mode then I'd be able to use it for
input and output.

This is the information that I got from the script,

Thank you,
            - Madura A.

Please also attach it next time, so no browser is needed to view these
details.

        !!Linux Distribution

Since you are using Ubuntu 10.10, the easiest way is to follow their
instructions to solve sound related problems and report it them using
`ubuntu-bug audio` [1]. There are several developers working for(?)
Ubuntu who will probably be able to help you really quick.


I am sorry to not be able to help you right away. Thanks,

Paul
