Thinkpad T400 - internal mic doesn't work, can't set CAPTURE - schematics included

[Arkadiusz Miśkiewicz]

Hi,

My Thinkpad T400 (2764CTO model) doesn't have ability to set CAPTURE on 
microphone inputs with alsa. Most likely some quirk is missing.

The laptop has internal microphone, microphone in input, headphones out output 
and 2 internal speakers. That's all.

Is uses Conexant CX20561_15Z internally and there is detailed T400 schematic 
available:
http://kythuatphancung.com/download/lenovo-thinkpad-t400-schematic-
diagram.html?dl
(for audio look around page 43).

Kernels 3.7.x, fresh 3.8 - no luck. Tried even linux-next from today but it 
dies early on alsa unrelated issues.

I've tried model options laptop, hp, hp-dv6736, hp-700, toshiba, ideapad, 
auto. None of these work fine. With model=hp-700 I can set CAPTURE but it 
doesn't work (silent audio is captured using arecord or in google hangout). 
External mic connected also doesn't work with these setups.

http://www.alsa-project.org/db/?f=394ff4cdca33e75c8a47203d42b89d8de36deca7 
[3.8 kernel]

http://www.alsa-project.org/db/?f=302877e50f99835075d038207f6db0dfd89873b0 
[3.7 kernel]

Thinkpad is 2764CTO model exactly. 

I can test various hacks, patches etc easily. Could someone look at schematic 
and provide quirks to test?

Thanks!

Hi,

What do you mean with "doesn't have ability to set CAPTURE"? What input 
is used is automatically selected depending on what you have plugged in, 
and its level is set using mixer controls (which in your alsa-info is 
set to minimum levels).

On some other notebook I had mic input that I could set to CAPTURE mode using 
space in alsamixer F4: Capture menu. Here I can't set capture on any of inputs 
(pressing space causes no change).

There are two jack sockets in this laptop, one with headphones icon and other 
with mic icon (on the laptop case itself) as on this photo:
http://www.notebookreview.com/shared/picture.asp?f=42200

Ok... maxing all mixer controls and connecting external microphone I get 
external mic being recorded. The mixer controls that seem to be working in 
such mode are: "Mic", "Mic boost" and "Digital". What's weird is that when 
"Digitial" is set to 0 then no sound from microphone is being recorded 
(testing with arecord -f cd | aplay). The "Mic" and "Mic boost" seems to work 
as expectedf. Question: why "Digital" has any influence here?

Unfortunately I'm unable to get internal microphone working at all. Even with 
all outputs set to maximum like this:

Internal mic is my primary problem.

Thanks!

We're increasingly moving away from manual input selection to automatic 
based on what is plugged in.

 From a quick look at the alsa-info things look fine, so I don't know 
what has happened here. Is it a regression from an older kernel, or did 
it never work?

Do you mean dynamic adc switch does not work as expected or "Dock mic
capture volume" and "internal Michael capture volume" controls cannot share
the same amp in ?
