Re: [Mactel-linux-devel] [PATCH] Audio in MacBook v2

Well, I really don't know, if my macbook is the second generation. Now I
found out, that there is probably a third generation of macbooks.

My macbook is the latest generation. So don't stone me if I wrote a bad
generation:-)

Yes, from the output you wrote, it seems, the patching was successful.

First at all, it is a good idea to determine, which version of macbook, or
more precisely which audio subsystem is used in your macbook. You can do
it by the command

# cat /proc/asound/card0/codec\#0 | grep Subsystem

If your output is an other number than 0x106b2200, there no chance that
this patch will work for you.

But, it seems, your mixer is not set correctly. Your input source is
set to "Line" and not for "Mic". I don't know if you tried some other
possibilities, but setting the input source as "Mic" would be necessary.

The last thing is, that I'm not an alsa developper. So I really don't
know much about alsa subsystem. This patch only provides some pinout
settings, which I actually took from the windows driver inf file.

Ok, I have the right version ;-)

Subsystem Id: 0x106b2200

Oh thats right, I oversaw also the hints on
http://wiki.debian.org/MacBook#head-d374bb9e1b7183c133759a8c6877a34c50c4ba7d

Will give it a try soon.

Thanx...

Well, the output of amixer is attached.

It was a bit surprise for me, that when I tried to record something,
my microphone was not working too. Fortunately, I was able to set the
mixer so that the microphone works now:)

I think the important things are setting the "Digital" and "MUX" controls.
It is a good idea to tune this settings for better record.
Probably there are more things, which are significant for recording. Just
look to my mixer settings.

I read somwhere, that it would be necessary to switch between "Line" and
"Mic"
as input source on startup. Well, I am not sure, if the _hack_ is
necessary,
because, when trying to setup correctly the mixer, I switched it. And I
don't
want to restart my computer now to test if it is really necessary.

Well, I don't know, what you are writing about:-)

I am not sure, but I think, there is not much to set in kernel config
for the soundcard.

Which mixer do you use? For example, it is necessary to run alsamixer
with options '-V all' to see the "Digital" control.
This is the only idea, which I have. If you really don't have the
"Digital" control, I really don't know what can you do:-(
