Currently the default model that gets selected on this hardware is "F1734".
Using this model neither the volume-wheel nor microphone (internal or
external) work.
The first part of my patch changes the default model to "fujitsu", this
enables the volume wheel on the left side of the laptop.
The second part changes the capture settings and thus makes it possible to
record from microphones. Now when capturing from the external microphone I
can hear myself talking but its quite quiet. I can improve this a little by
raising the capture volume, but if I raise it above 40 I can no longer
record anything.
Questions:
Is this patch any good or is there a better way to fix my problems?
Why is the recording so quiet and why can't I record with capture value
above 40?
