snd-hda-intel: Fix volume-wheel and microphone on Fujitsu-Siemens Amilo M3438G

snd-hda-intel: Fix volume-wheel and microphone on Fujitsu-Siemens Amilo M3438G

[M G]

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?

Thanks for your patch.

The concern is whether you lose any functionality by this rename.
The support of the volume knob control with the existing F1734 model
would be easy.  You'd need to add a proper verb to enable the
unsolicited event and register the handler, such as, uniwill_p53 one.

Using 6stack_capture_source looks wrong to me.  It is actually for
desktops.  But yours isn't, I guess.

The recording quality might be improved by setting the proper pin VREF
level.

Anyway, it'd be more helpful if you can show the detailed information,
e.g. the output of alsa-info.sh script.

No, it's a Laptop. The standard capture source has front mic at 0x3
while the 6stack capture source has front mic at 0x1; this is the only
difference but this seems to be what makes it work, I don't know why.
(Btw: It is always front mic, no matter what microphone I use. As soon
as I plug the external mic the internal one gets muted and the
external one takes over it's channel)

About the technical stuff: I don't know what an unsolicited event or a
VREF is, I'm not a programmer. I just fiddled around with stuff until
it was working but don't understand it :)

I have uploaded the output of alsa-info.sh twice. First with normal
alsa und then with my patch (don't know is this is important)

OK, then I think it's better to change the existing F1734 stuff rather
than moving to model fujitsu.  Model fujitsu is, apparently, for the
distinct int/ext mics while yours has only one mic input regardless of
connection.

Was the headphone muted automatically even without your patch?

Connecting a headphone automatically mutes the speakers; it has always
been this way.

The effects of your patch are the same as with mine, i.e. good.

I think this might also need to be changed then?

It has already been a great improvement but I encountered 2 more problems:

On first use (i.e. when loading the module for the first time after
compiling it) the mixer displayed Mic as capture source but I couldn't
capture anything. When I switch to CD and then back to Mic it starts
working. It seems that the value is initialized to 0x00 but there is
no corresponding capture device on this model since the mic is 0x01 so
it needs to be initialized to 0x01.

Another thing: I can set the capture volume to a maximum of 14dB.
Above that the quality starts to degrade rapidly and at about 17dB it
goes completely dead. With VREF50 I can raise the capture all the way
up to 35dB.

Thanks for the patch.  Could you give your sign-off together with a
proper changelog to commit to the upstream?
