Microphone does not work on wheezy laptop.
 

Good time of the day.


Please help me to make my mic. working on wheezy laptop. It has

[AMD] nee ATI SBx00 Azalia (Intel HDA)

sound card. Though mic work in laptop built-in test suite (called on
key press at boot), amixer shows no mic:

Simple mixer control 'Master',0
Capabilities: pvolume pswitch penum
Playback channels: Front Left - Front Right

Front Left: Capture 0 [0%] [0.00dB]
Front Right: Capture 0 [0%] [0.00dB]

- this is complete its output.

Please share any ideas on what can be done to make mic. working.

Thanks for Your time.

That info is not enough to identify your hardware properly :-)

Run these command and put here the ouput:

cat /proc/asound/cards
head -n 1 /proc/asound/card0/codec*

It can be that sound card is not being properly detected and you need to pass
the "model=" parameter to the ALSA config file. Depending on the codec and your
kernel verion, you can edit the alsa configuration file and append to the
"options" line a value that matches with your sound card hardware settings:

http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt

It can also be that your sound card chipset is too new for your kernel or alsa
version but that would be strange given that your're on wheezy. Was the mic
detected before or has never worked?

What do I miss here?

I have searched through the list for "HDA-Intel" - but did not find it,
but at the same time I have found corresponding line for my laptop
model, so I've got the module is called

dell-m26

Now, where should I put it? Can You bring here the line example?

My kernel is 3.2.0-3-amd64.

Opposite, it is old laptop. And the situation w/ mic was ever that way.
I'm just trying again to make it working.

I don't know... I just have run the above command from my wheezy
(installed in a netbook) and I got a reply ("codec: IDT 92HD88B1") :-?

Check if there's something of interest in the directory, try with:

ls -la /proc/asound/card[0-9]/*

And also run "aplay -l".

Before going to the list of HD Intel codecs and select one, you have
first to know what codec uses your soundcard :-)

Oh, good catch, you can try with that but do you really have an "Inspiron
1501"? :-?

> Now, where should I put it? Can You bring here the line example?

This has to be placed in "/etc/modprobe.d/alsa-base.conf", at the end of
the file add new line similar to this:

options snd-hda-intel enable=1 index=0 model=dell-m26

After editing the file restart the alsa service or reboot, which is
usually easier.

(if there's already a line starting with "options snd-hda-intel ..." just
append the "model=dell-m26" parameter and keep the rest as is)

The most recent kernel version is usually the better for hardware
support :-)

Mmm... if it was working before the chances that the card is still
supported are higher. It could be just that now it requires some tweaking
or specific settings to make it to work :-?

Oh, it's better:

That gives us same

Thank You very much! - What did You check to find out that
"snd-hda-intel" should be specified here? - I understand that
"HDA-Intel" tells about this - but what about exact "snd-hda-intel"
cypher? :o)

I have done as You said:

Hmm. I do not think the lap. is too old that the code will be removed
from kernel/ALSA to support the HW. You know at the time laptop was new
and latter - I thought, When will kernel support my mic. ? And You say
it is old. I think it is misconfiguration on ALSA/whatever side that
withheld mic. from working rather than a support issue.

If You will not get borried w/ the thread, I will supply any info
needed in order to solve the mic. problem.

Again. thank You!

Not yet :-)

But also run:

cat /proc/asound/card0/codec#* | grep Codec

Because you seem to have two different codecs listed.

Okay, okay... let's try then to restore the honour of your oldie laptop.

Mmm... that's the usual value for intel HDA chipset (the full list of
available modules are documented here):

http://www.kernel.org/doc/Documentation/sound/alsa/ALSA-Configuration.txt

(yours is and HDA ATI SB)

Wait. I must have missed this line from your very first post, but this
has to be your mic input (this is what I also get from my netbook and I
can from the mixer applet the "mic" is there) :-?

How are you testing your microphone?

> - no mic. nor mic. working. :o(

Well, you can also try with a different one as this won't hurt:

options snd-hda-intel model=ref

And so on... (remember to reboot or restart alsa service after editing
the file to changes take effect)

Neither I do. That would be going very (very) backwards.

Yup.

Bored because of problems... never! That makes things even more
interesting :-)

Let's see if we can restore your recording capabilities.

Hmm. On desktops I see exactly word microphone or mic - do not remember
correctly. Then alsa mixer has appropriate handle w/ which I can change
its gain. - Here, on laptop, I miss all this.

> How are you testing your microphone?

Eventually, knocking on microphone gives no any sound in speakers.
Whereas on desktops - it does.

The microphone is working - tested on desktops.

Done, restarted w/

correct? - But nothing.

What do you mean? :-?

The above "head" command should look for whatever files are placed there,
remember we used a glob pattern "*" so any "/proc/asound/card0/
codec_whatever_file" has to be found.

So it seems.

Yes, that makes sense. Conexant is a well-known manufacturer for embedded
modem chipsets.

Good. I wanted to verify the STAC92xx chipset was selected as the default
recording chipset instead the other.

Shhh! Be quiet, your netbook can be listening and won't like seeing
you're in doubt about it :-)

Yes, I also see a "Mic" device in desktops but not in my netbook (and you
know what? My netbook also has a STAC92xx chipset, I didn't notice until
now :-P). I mean, this can be normal and not an error per se. Of course,
despite not being displayed, the microphone has to be visible/
controllable from the sound applet and has work :-)

And now I realized I share the same chipset as yours and we also share
the same kernel version, I can run more tests from my side. Run "dmesg |
grep -i mic", I can see a line referencing the microphone device, check
if you also have it.

Okay, have you checked for the input (mic) volume levels? What kind sound
controller are you using (gnome/kde volume applet...)? Also, test with
the usual command line utility to test the mic:

arecord -d 10 /tmp/mic.wav

The above will record from your mic input for 10 seconds and save the
sample result at "/tpm/mic.wav" which you will be able to play with:

aplay /tmp/mic.wav

Mmm... maybe this indicates that specifying a model by hand is not needed
and the problem is elsewhere :-?

Good time of the day, Camaleón.


Thank You for Your time and answer.

That "the "head" command returned void" - therefore no microphone?

No, it doesn't here - the mic. does not function! I can say
anything about for the present time. :o)

And w/ this I have problem. I use console only tool - therefore I use
ALSA mixer, and my mic refuses to work unless in it is the built-in
(ROM?) testing program. May it worked under windoze - but I had never
such a one on the lap.

Does Your mic. work?!

Of course. I just checked now and to my amasement I saw additional
channels appeared. So, I have turned on all of them w/ maximum gain:

Yet, no sound from the mic.

This command hangs - I think it can not use/open mic. device if any.

Well, it returned "nothing" but there were indeed two devices, so no
"void" at all. That was my concern, that "head" command was "lying" us :-)

There's still the modem mic!! :-P

Mmm... is it possible that you can you load a LiveCD (choose whatever you
prefer, it does not have to be Debian or Debian related) and check if the
microphone is present there? I mean, that you can controll it from the
sound applet.

> Does Your mic. work?!

Good question as I don't use it so much :-). Hold on, going to test it...

Yes, it works. I have launched the gnome-sound-recorder application and
from there I can only select one device ("master") from where to get the
input. I start recording and after stopping and playing I can hear
exactly the recorded sample.

Let's see how it goes with the "arecord" utility. Hold on...

Yup, it also works fine.

Hint: when you're in alsamixer, press F6 to be sure you are controlling
the right card (Intel HDA) in the event there is more than one listed.
Also, from here, press F4 to put at 100% the Capture swicth.

Three (3) inputs? I only get one. I wonder if the mess can be from here :-?

Uh? Magic strikes back? :-)

Capture is "off".

Here there's a difference with mine: I have both (front left/right)
turned [on].

For these ones there's no info about if they're on/off.

Mmm... that's curious. If the mic is not detected (not your case) or not enabled
(this seems to be your problem) I would have expected an error from arecord but
not to hang :-?

While Googling around, I found this:

https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#No_Microphone_In put

You can try what it says, that is:

***
Many Dell laptops need "-dmic" to be appended to the model name in /etc/modprobe.d/modprobe.conf:

options snd-hda-intel model=dell-m6-dmic
***

Yes, not very orthodox, but you seem to have a "new" digital mic detected, so
who knows... Also, take a look into ALSA debigging tips for recording:
