[20ALCTO1WW, Realtek ALC292, Black Mic, Left][Lenovo ThinkPad X240] external mic has no sound at all

[doctorow]

During this test, an error dialog was thrown, reading:

The following mixer control(s) might be incorrectly set:
Mic is at 0.0%

Mic is muted
Please try to fix that (e g by running
"alsamixer -D hw:PCH" in a terminal) and see if that solves the problem.
Would you like to continue troubleshooting anyway?

However, the System Settings... -> Sound UI shows the mic as not muted. When I tried running the alsamixer command, I saw mic and mic-boost were both showing 0; I cranked them up to 100, but it made no difference. I also tried re-running this command with the mic/mic-boost still set to 100 and it threw the same error.

Lenovo ThinkPad X240

@taihsiang, can you grab the package oem-audio-hda-daily-dkms from https://launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa-daily?field.series_filter=trusty and check again if the problem still exist?

[David Henningsson (diwic)]

Looking at http://www.ubuntu.com/certification/hardware/201307-14019/ it seems this machine was pre-installed with 12.04.2 LTS.

Checking the kernel source does not find anything that should have regressed nor fixed external mic on this machine, so next question would be:
 - Is this working on the pre-install image or was there a miss in the testing?
 - Is there any specific audio patches (e g an alsa daily dkms) applied to the pre-install image?

[Taihsiang Ho (taihsiangho)]

The following headsets were tested on Lenovo ThinkPad X240 (CID 201307-14019) and
could reproduce this bug.

They are[1]:

OMTP: Nokia WH-102 HS125
CTIA: SONY MH-EX300AP, Samsung (unknown model), HTC (unknown model)

[1] It is hard to know which type the headset is because there is no model label, and
even there is a model label, the data searched from internet seems to be unclear or very few.
I confirmed the type by the brands because of history background of the development of the pole standard, and
a electronic multimeter to measure the resistance of the poles of the headsets.

The combo audio connector does not support a conventional microphone.

Combo audio connector
Connect headphones or a headset that has a 3.5-mm (0.14-inch), 4-pole plug to the combo audio connector to listen to the sound from the computer.

[Taihsiang Ho (taihsiangho)]

When mute mic key was pressed, mic LED did not turn on/off, but the volume status bar (unity notification) would pop up and show the speaker was muted/unmuted. However, the speaker does not be muted practically.

[David Henningsson (diwic)]

Could we check whether it's the jack detect or the signal which is at fault here?

To do that, install the alsa-tools-gui package and start hdajackretask. Select the analog codec, check "advanced override" and for pin 0x1a (Mic), change "jack detection" to "not present". After applying the change, now both the "Internal Mic" and "Mic" options should always be available. So plug your headset in and manually switch to the external mic.

What is the result now, e g:
 - recording from external mic?
 - recording silence or random buzz noise?
 - recording from internal mic although the external is selected?

[Taihsiang Ho (taihsiangho)]

recording from external mic?
- No sound.
recording silence or random buzz noise?
- random buzz noise. Please refer to the attachment external-mic-sound.wav
recording from internal mic although the external is selected?
- No. Please see the following description[1]

[1]
select internal mic, unplug external mic: there is recorded sound
select internal mic, plug external mic: there is recorded sound
select external mic, unplug external mic: silent (mic amplitude > 100%)
select external mic, plug external mic: ramdom buzz similar to the attachment external-mic-sound.wav

you need to use debug version of alsa driver to check the system log to find out whether your codec alc292 can automatcally differentiate headset and headphone as your thinkpad does not support conventional mic

Thanks. Could you please also submit alsa-info for case "select external mic, plug external mic" where the recording is noise?

In addition, could we check the jack detection in detail: Please install alsa-tools 1.0.28 (if you're running trusty, it's available from https://launchpad.net/~diwic/+archive/ubuntu/hda ) and the do the following:

Ok, so the jack detection is working correctly.

Next step is to try if X240 uses a non-standard VREF of 50% instead of 80%. I'm attaching a DKMS for you to try.

[David Henningsson (diwic)]

Please remove any changes done in hdajackretask or /etc/modprobe.d/alsa-base.conf (if any), install this DKMS (under a 3.13 kernel), reboot, plugin headset jack.
Now try recording and check the result. If the recording result is different from previous recording, please attach it.

Also an alsa-info taken during recording would be appreciated. Thanks!

[David Henningsson (diwic)]

For reference, this is the patch applied to the DKMS.

@Raymond
Thanks for your information.
I will find time to give it a try.

[David Henningsson (diwic)]

This seems to be a tricky one. I was wondering if we can also make a coef dump. To do that, please do the following:
 1) revert any changes done with hdajackretask or /etc/modprobe.d/alsa-base.conf
 2) on top of 14.04, install the latest daily dkms package (from the alsa-daily PPA)
 3) reboot
 4) (as root) echo 1 > /sys/module/snd_hda_codec/parameters/dump_coef
 5) start recording to headset mic and confirm that the bug is present (records buzzing noise instead of clear sound)
 6) while recording is active, dump alsa-info
 7) attach alsa-info (or a link to it) here

Thanks!
