[alsa-devel] Thinkpad T400 - internal mic doesn't work, can't set CAPTURE - schematics included
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=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).

Hi,
What do you mean with "doesn't have ability to set CAPTURE"?
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).
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).
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.
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).

Internal mic is my primary problem.
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 ?
