Microphone not working in Ubuntu 18.04.3 LTS on new hp-spectre-x360-convertible-15 laptop

Probably on this machine, the internal mic is connected to pin 0x13.

Pin 0x13 does not work as well. Overriding pin 0x13 to use the Internal Mic causes an undesirable side-effect of static noise in any plugged in headphone.

I managed to solve the issue by downloading the .deb file specified here - https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1523100/comments/72. After installing it and then rebooting, the mic started picking up sound.

NOTE: The complete solution involves:
1. setting the internal microphone to be mapped to the pin 0x12 using alsa-tools-gui (hdajackretask) and then rebooting
2. Downloading and installing the .deb file mentioned above and then rebooting.

Sorry, but this works only with my headset plugged in. If my headset is not plugged in, then the mic again does not work. So #3 is a partial solution.

Unfortunately, this has stopped working, ie. even when the headphone is plugged in, the mic no longer works. Would really appreciate it if anyone could help me with this problem. Will be happy to provide more info if required.

You said the internal mic works well under windows10, so please run this dump program under windows10, then upload the dump file to launchpad, maybe we can find some difference from the linux.

Running the program in Windows gave me a Blue Screen Error.

@hui.wang

Sorry for the late response.

I have now managed to make my headset mic work permanently. I had to add the following line to the file /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel model=alc295-hp-x360

However, after doing this, a week later my speakers stopped working and I had to change some pin mappings using alsa-tools-gui: specifically I used Pin 0x14 for Internal Speaker (LFE) and Pin 0x1e for Internal Speaker.

So right now, my speakers work, my headset(mic + sound) works and only my internal mic does not work.

I am still unable to run the dump program in Windows. However, I can tell you that my laptop has Intel Smart Sound Technology(SST). I read somewhere that Ubuntu still does not have proper support for that although I may have misunderstood what I read. So I am not sure.

I am having the same problem with a new dell-g3-3590,

arecord -l gives:

Its not detecting the internal mic nor the headfone mic.

indeed, the headphone mic is working perfectly, so it`s not detecting the internal, i am still to test the internal mic in others SOs to attest that is an alsa-driver bug.

It seems to be a problem from the chip series itself since in 16.04.03 it also does not get detected. Or the internal mic is flawed, I still need to test in windows 10 to be sure if it is a alsa driver problem to this chip or a hardware problem

Suddenly my mic stopped working too, it is a ThinkPad T480s. It worked a couple of weeks ago last time I tried it.

When setting the input level to max, I can see a faint signal on the visual input bar.
Any suggestion how to see what is wrong?

Hi all, I have the same problem,

My notebook is the same @dkajah, a new dell-g3-3590 with fresh Ubuntu 18.04LTS install (I already test with 19.10, the result was the same.

Status changed to 'Confirmed' because the bug affects multiple users.

Same problem here, the microphone shows as (unplugged) in the PulseAudio Volume Control. Ubuntu 18.04.3 LTS.

So for the hp-spectre-x360-convertible-15 laptop, probably the internal mic doesn't connect to the codec, it connects to the PCH directly. So setting 0x12/0x13 to internal mic doesn't work at all.

Please install this testing kernel, then boot with this kernel and upload the dmesg, Let us see if the dmic connects to the PCH or not.

thx.

I have the same issue on a HP Spectre Folio 13 with Xubuntu 18.04. Internal microphone does not work. Headset microphone is detected when connected through a usb-c hub.

I believe I'm having the same issue on a Dell 7591 15" 2-in-1 running Ubuntu 19.10. With no headset plugged in nothing shows up under Sound->Input. If I 1) plug in headset (select Headset in the pop-up) 2) Open Sound 3) Select Microphone Built-in Audio under Input 4) Select Headset Microphone under Built-in Audio...then input audio is picked up but is scratchy as OP mentioned.

I have the same issue on a HP Spectre Folio 13 with ubuntu 19.10. Internal microphone does not work. Headset microphone is detected when connected through a usb-c hub.

I have the same issue on my HP Envy 15 x360. Internal microphone isn't detected, but headset microphone is when it's plugged in.

I have the same issue with my Lenovo Thinkpad. The internal mic doesn't work, but when using a headset the mic works.

I have confirmed that my Dell Inspiron 7590 with Realtek alc3254 also have the issue with built in microphone.

Has anyone found a solution to this problem? I have it too, my computer is an HP Envy x360 Convertible.

Any help would be greatly appreciated!

Same issue on Dell G3-3590 i7 gtx1660, worked for 2 months and now simply stopped, started without audio that i solved with this:

" I used to change /etc/default/grub to have this line

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012' snd_hda_intel.dmic_detect=0"
Then run in terminal

grub-mkconfig -o /boot/grub/grub.cfg "

I get this solution from here:

https://bbs.archlinux.org/viewtopic.php?id=251157

Now audio works fine, with and without headphone. But the problem now is that the internal microphone is not detected. And when the headphone (with dont have microphone) is connected he is detected in input devices list as if it was a microphone.

and when I added this: options snd-hda-intel index=0 model=laptop-dmic
on: /etc/modprobe.d/alsa-base.conf

a internal mic appears in the input device list but still not detecting audio, and the headphone is not detected in the input list anymore, but audio still working...

same on my Dell G3 15 3590 no sound after updating to kernel 5.3.0-42. The mentioned workaround in #28 solves the issue for the speakers. However, only 'snd_hda_intel.dmic_detect=0' was necessary.
I tested the mainline Kernel (5.5.11) with the same result but here one has to use 'snd-intel-dspcfg.dsp_driver=1' to the sound running again.
(found it here: https://bugzilla.kernel.org/show_bug.cgi?id=205959)

as in #28 the microphone is still not working yet but with the addition of 'options snd-hda-intel index=0 model=laptop-dmic' to '/etc/modprobe.d/alsa-base.conf' it appears for the first time.

I am on the HP 830 G6 and with 'options snd-hda-intel index=0 model=laptop-dmic' I finally see the microphone appearing in pavucontrol. However, I cannot get the microphone/input working.

Currently, I have the following lines added to make at least output sound working and *see* the microphone in pavucontrol:

options snd-hda-intel dmic_detect=0
options snd-hda-intel index=0 model=laptop-dmic

Reproduced on `Acer Aspire VN7-592G`. Runnung on Ubuntu 19.10, kernel version 5.3.

Firstly had no sound devices detected at all. Adding
`options snd-hda-intel dmic_detect=0` to `/etc/modprobe.d/alsa-base.conf`
Fixed the issue and sound appeared.

But after that found out, that no input sound device is detected by system, along with headset mic.
adding
`options snd-hda-intel mode=aspire-headset-mic`
resolved issue for headset, obviously, but still no default input device is detected by system.

Also've been trying to use
`options snd-hda-intel index=0 model=laptop-dmic`
after that. Device appeared in sound panel, but it's recording only static noise, nothing more.

Still finding a way to resolve issue for built-in mic.

I have the same issue on my Dell G3 3590

I "fixed" output (https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html), on similar way as others, but input / internal microphone remains undetected (unplugged, as pulse audio says).

External microphone works fine and it saves me for now.

Have the same issue on a lot of laptop in my company, we have a webteam that work with Ubuntu and i update all machines for the last version 19.10, after this update all laptops don't have a internal micro.

Model: HP 830 G6

Same insue here with a Dell G3 laptop. Microphone, nor any input device its recognized

I have an Asus laptop with an internal mic. I have Ubuntu 19.10 on it and the mic will not work. I've tried everything I can think of but with no luck:( Somebody please fix this.

Facing the same problem with an HP Spectre X360, I tested several distributions and several different kernel versions.

I also followed several guides explaining how the problem could be solved, but none worked for me. What I find curious is that in Ubuntu 19.10 and 20.04 in live mode the microphone works perfectly (both internal and the headset).

I copied the contents of the alsa-base.conf file from live and overwrote that of the distribution, but it also didn't work.

Tested with kernel: 5.0x, 5.3.x, 5.4.x, 5.5x (family 4.x bring other problems for my hardware)

I was also able to use an external microphone using a USB adapter.

I have the same issues on an HP ENVY x360 Convertible 15-dr0xxx. I have tried about everything I could find online about this issue but the internal mic still isn't working. :(

I have the same issue with an Acer Swift 3 SF314-57 58D5.

Now running ubuntu 18.04

At first neither speakers or mic were working. I managed to get the speakers working by modifying the file /etc/modprobe.d/alsa-base.confn adding a lines at the end "options snd-hda-intel dmic_detect=0" [without quotes].
/etc/
The output for "arecord -l"

is as follows:

"""

Tried adding "blacklist snd_soc_skl" to the file /etc/modprobe.d/blacklist.conf

No solution still found.

I have the tried solution from https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X1_Carbon_(Gen_7) and it seems to have worked for me on Arch! You can also have a look at https://gist.github.com/hamidzr/dd81e429dc86f4327ded7a2030e7d7d9

Similar to #30. Curiously, audio and mic worked for a few days when adding
   options snd-hda-intel dmic_detect=0
then mic disappeared. Mic reappears but doesn't work after adding
   options snd-hda-intel dmic_detect=0
   options snd-hda-intel index=0 model=laptop-dmic

Is this bug something that is actively worked on or is it ignored until 20.04 is released as stable (Regarding to https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1840725/comments/37 in 20.04 the mic works)?

I've had an HP Spectre 360 with HP dock for 5-6 years, and this has always been a problem, and it still is. I traced it down one time to the script that detects the available audio input devices, and sets the default. The script is poorly written and is hard to follow. It detects that there are two microphones. Then correctly sets the default microphone to what the user specified, but then it sets it again, to the last microphone detected. In my case, it was the non-existant microphone on the HP dock. This script got written over by some update, and I haven't had the time to track it down again.

I'm still seeing this in 20.04 beta, the difference is now it no longer remembers my selections for using the internal speakers, or the internal microphone. It defaults to the non-existent dock speakers and microphone every time I reboot.

The only way I could get the internal microphone to work was if I booted without being attached to the dock, then attach the dock after I logged in.

This also affects me. HP Spectre Folio AK13. I added
 options snd-hda-intel dmic_detect=0
 options snd-hda-intel index=0 model=laptop-dmic
as descrived above.
Now the sound works (again, it worked initially after install). Mic shows up after adding the last line and the sound works (again), though as "back-mic built-in" (in norwegian Bak-mikrofon - Innebygd enhet) in Settings - Sounds.

Running 19.10 with the latest kernel updates (as of today).

It would be really nice to have working microphone now with the lockdown and everything.

I tried using the:

options snd-hda-intel dmic_detect=0
options snd-hda-intel index=0 model=laptop-dmic

in /etc/modprobe/alsa-base.conf

All it did for me was add a new microphone to the selection list in the settings. Neither build-in selections work.

Spent a little time looking through some files, but didn't find anything that stands out. It will take some time looking through files, and scouring websites. I might spend some more time looking into it again, because I find myself needing a microphone lately. and, I have a little time on my hands lately.

I'm HP Spectre x360

The internal microphone is not working for
System76 Gazelle gazp9 which is a Clevo laptop under the hood.
Ubuntu 18.04.4 LTS bionic

I think I did a Zoom interview a few years ago, and it worked, but the microphone hasn't worked for the last few months.

This is an old laptop with two input jacks, one for microphone, and one for head phones. My headphones have a combo mike in the cord. Maybe if I had a separate microphone, it would work. Or if I had a splitter.

But when nothing is plugged into the mike jack, the internal microphone does not work. The input settings have an orange bar that is supposed to oscillate if it picks up sound, but nothing is shown on that when I speak. If I put my combo cable in that jack, it briefly oscillates, but that's like a fluke. Something is live there - maybe the device is recognized - but it's not working.

Sorry - mine is working now, you can delete the above message. With help from System76b tech support, I had to install pavucontrol and turn the microphone (input device) way up. Then I tried recording my voice in audacity and it's horribly scratchy.

The scratchiness was fixed in alsamixer, by setting mic boost to 100, and internal mic boost to 0.

Sorry to post so much - I wish I could consolidate or edit all these posts. The next day I came back and it didn't work in Zoom. I tried a bunch of things listed on the following web page, starting with simplest first, from

https://support.system76.com/articles/audio/

until finally I did

sudo apt install --reinstall alsa-base alsa-utils pulseaudio linux-sound-base libasound2

then I rebooted and

sudo alsa force-reload

and it worked. Which is weird, I think, because I just did this reinstall of these modules 3 days ago. I don't think the versions of these modules changed. I don't know what's going on. My guess is that it breaks because something changes a configuration file. And then I guess it's fixed when the configuration file is re-initialized by re-installing these modules. I wish I could pinpoint it.

As mentioned in comment #37 the internal mic works well with Ubuntu 20.04 live mode. I haven't tried installing Ubuntu 20.04 though, as some report the mic doesn't work once installed.

I wish I knew more and had the time to understand the difference (beyond kernel) between Ubuntu 20.04 live mode and non-live mode.

I'm currently running Ubuntu 19.10.

Let me know if there is something I can test to understand why Ubuntu 20.04 live mode works.

Thanks

It stopped working again, and rebooting fixed it. I also ran some scripts when it was working and not working, attached here.

Here's the attachment of the script when the internal microphone was working.

A thing noticeable about the diff of the working and broken internal microphone is that the one that's not working shows the processes that are accessing the sound card (pacmd list-clients) includes libcanberra.

The other thing I wondered about is that in the broken one, the IRQ pin numbers reported by "cat /proc/asound/cards" and "lspci -vvv | grep -A9 Audio" are different.

I don't know if this has anything to do with why this internal mic stops working. I wonder what is calling libcanberra.

Then it stopped working again, but this time libcanberra is not shown by "pacmd list-clients", so maybe that has nothing to do with it.

Same issue, dell g3 3950, on mint

Managed to fix the audio using

> options snd-hda-intel dmic_detect=0
> options snd-hda-intel index=0 model=laptop-dmic

too, and can now see the microphone, but it doesn't record anything

I can confirm that the update to 20.04 fixed the audio and microphone for me!

Same laptop as #58 but, update to 20.04 hasn't worked for me.

@rolfinator, can you tell us anything else about your setup or changes before/after the update?

I have the hp spectre x360 13 convertible and the update to 20.04 did not work for me either.

Asus Gl703VD has the same problem Ubuntu 20.04

Toshiba Satellite Radius 12 C-720 same problem ubuntu 20.04

I fix it on ubuntu 19.10, maybe work on ubuntu 20.04

And then surprisingly this thread helped (see https://gist.github.com/hamidzr/dd81e429dc86f4327ded7a2030e7d7d9#gistcomment-3315737 ).

What I've done is I appended next two lines to /etc/pulse/default.pa:

# /etc/pulse/default.pa
load-module module-alsa-sink device=hw:0,0 channels=2 # note that I used 2 here
load-module module-alsa-source device=hw:0,6 channels=2
```

For those of you having problems in Ubuntu 20.04 with Realtek ALC285 this could be a solution.

On Ubuntu 20.04?

#63 + #65 combination worked for me on
HP 830 G6, Ubuntu 20.04 .
Thanks!!!

I'm using an HP Omen. Ubunut 20.04
I have the same Mic problem.

Speakers working
HDMI connection (never tested)
Jackplug mic working
"Rear mic"/"internal mic" not working.

Internal mic "not pluggedin" according to Pulsaudio
Rear mic equalizer registers sound when playing audio on computer.

I've tried so much I don't know what I've done or not done. But I can say
removing
"options snd-hda-intel dmic_detect=0" (see comment 65) switched the output back to "Dummy Speaker" and I lost all audio.

Audio/Mic all fine in Windows boot.

I can confirm that a clean installation of 20.04 fixed the issue on my HP Envy 15 x360. The internal microphone is properly detected and working.

Have you tried an Update to 20.04 before?
What Hardware do you have in the Envy 15?

#63 + #65. internal mic is working but not with external mic. 3.5 jack audio on asus TP410 Ubuntu 18.04

Still having the same problem on my ASUS laptop running 20.04. There's been various updates and things since I last posted but none of them have fixed it! I'm hoping for a fix soon.

Hi,

Since recent updates :
 - External mic (in headphones) : Working
 - Internal mic : Not Working / Not recognized

HP Omen. Ubuntu 19.10. 5.3.0-59-generic #53-Ubuntu

+ External (bluetooth) input working
+ External (bluetooth) output working
- Internal input not working (nothing shown)
- Internal output not working (Dummy shown)

Managed to fix internal output by adding "options snd-hda-intel dmic_detect=0" after reading comment #69. Perhaps it was here before because I lost "internal output" couple of months ago after messing with these settings.

Internal input still not working.

Hi HP OMEN 17 cb0000 (2019) with the same issue.
Thanks to #63 and #65 I got somewhat working the audio but not the internal mics yet.

What happens here is that the Mic is a digital array. Is not the simple analog mic that always we use.

Intel SST mic array with the realtek alc285.

This discussion maybe has the answer https://bugzilla.kernel.org/show_bug.cgi?id=201251

#63 and #65 did not work for me, resulted in dummy audio - #66 also did not work for me.

for #78 my specs

Hi. Dell Inspiron with Ubuntu 18.04.3. I had this issue for a couple of months. None of the above hints have worked for me. After today's software update, all is back to normal :)

I was having this issue, didn't gather much info on in, but I was on Ubuntu 18.x LTS, my Dell Vostro was detecting 3 mics, when I actually had only 1. I reinstalled Ubuntu, 20.04 now. At first glance it was detecting the same mics and some buzz noise, same with the 18.x, but then after the initial update, I restarted my pc and now it's all working, and it only detects 1 mic

Have same issue with my "HP ZBook 15 G6" (5CD025HRT7)

Problem on my HP x360 1040 G5 with the internal MIC: https://bugzilla.kernel.org/show_bug.cgi?id=201251#c231

Hi everybody,

Till today, I had issue with internal mic which was undetected (Dell G3 3590)

Few months ago, I updated my Ubuntu to latest LTS, 20.04.1
That didn't help. But... after a bunch of regular updates and upgrades, today, I have deleted line which "fixed" issue with dummy output/input.

file: sudo vim /etc/modprobe.d/alsa-base.conf
deleted line: options snd-hda-intel dmic_detect=0 => note that this command turns off mic (if I understand this part correctly dmic_detect=0)

After restart, internal mic works :)

Try it out! I hope that this bug is resolved for all of you.
Do not forget to update your Ubuntu to latest LTS. For me, this action passed without error.

i don't have dmic_datect=0 in alsa conf, only:
options snd-hda-intel index=1 model=laptop-dmic

if i delete this, i still have no mic.

Nothing to do for me. Ubuntu 20.10 HP spectre x360. 5.11.22 Kernel (no microphone)
