Lenovo Legion 5 - Internal Mic Not Working

Support Sound
1

Hello,

Just started using Manjaro last week and just cannot get the internal microphone to work.
I am running a Lenovo Legion 5 laptop which has an internal microphone next to the webcam.

Note the sound works fine, its only the mic.
I have been testing with Discord, but the mic bar is empty.

Here is the arecord -l info:

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC257 Analog [ALC257 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0

I have tried on alsamixer to set the volumes to max and making sure that the Capture device is activated:

I have followed the ArchWiki for troubleshooting the mic:

Followed also the other Manjaro posts about the mic not working, but none of the solutions posted there seemed to have been working. Last one I tried was creating a disable_dmic.conf file and putting the following setting:

options snd_hda_intel dmic_detect=0

Hope this is enough information, not sure what else to provide, but do not hesitate to ask.

Thank you!

when you started in to the boot loader did you switch to open source drivers or proprietary because alot of sound cards like intel sound cards use proprietary software which manjaro doesnt no include by default in the open source drivers like ubuntu or linux mint i think because i ran into the same problem you did and selecting proprietary software in the boot loader seemed to solve the problem for me on my machine is im runing a HP ENVY x360 Convertible 15-dr1xxx and my laptop like yours has a simlar sound card

Yes before the install, I researched the difference between the 2 options and made sure to select the proprietary option instead.

System data shows the Sound Open Firmware drivers to support the internal digital microphone array (dmic) are probably installed, but only in use as alternate drivers

Device-1: Intel Comet Lake PCH cAVS vendor: Lenovo driver: snd_hda_intel 
  v: kernel alternate: snd_soc_skl,snd_sof_pci bus-ID: 00:1f.3 
  chip-ID: 8086:06c8 class-ID: 0403

I suggest you check package sof-firmware is installed to make sure all the required drivers are available for ALSA

pamac info sof-firmware

The modprobe option mentioned in OP will only work to disable the dmic for kernel v5.4 and earlier

No output of speaker (heaphone and handset working properly)
this option has now been deprecated and does not work with kernel v5.8
If you want to continue using system with the internal dmic disabled
replacing the old modprobe option with `options snd-intel-dspcfg dsp_driver=1’
should get system working as before

Problem with headphones audio
The new modprobe option options snd-intel-dspcfg dsp_driver=1 might not be needed if the internal microphone array is supported by Sound Open Firmware drivers

It might be possible to change the modprobe option to force use of snd_sof_pci instead of snd_hda_intel

options snd-intel-dspcfg dsp_driver=3

If that option does not support the dmic for this system you may need to contact sofproject to consider if a driver patch is needed – Issues · thesofproject/sof · GitHub
I do not see any previous issues reported for a ‘Lenovo Legion’ system

Hello,

I ran the info for sof-firmware and it is installed:

Signatures            : Yes

For the option dsp_driver=3, as soon as I added that and rebooted my computer, audio stopped working entirely. Undid my change and rebooted my station, and now the audio is back, but the mic is still not working. I removed the disable_dmic.conf file entirely since it was not doing anything.

Side question to better understand the modprobe directory. How do you know which *.conf file to create in that directory? I have seen multiple forum posts that each had a different *.conf file with their own name (for example: alsa-base.conf and the one I used on my OP).

I will create a ticket on the SOF site and see if I get a reply. When I get an update, I will make sure to post it here.

Thank you so much for your help!

The modprobe option snd-intel-dspcfg dsp_driver= can use numbers 0-3 for loading Intel drivers
0 - auto-detect driver
1 - snd_hda_intel ‘legacy’ driver without internal mic support
2 - snd_skl_soc ( for 7th and 8th gen Intel CPUs)
3 - snd_sof_pci (for 9th gen or later Intel CPU including Comet Lake)

Most other audio modprobe options are for hardware specific motherboard or laptop patches

The name of the *.conf file is not usually important, as long as it ends in .conf
The files are read and processed by system in numeric alphabetical order so they can be named to load in a specific order, but it is not a problem for loading one or two audio options

On Archwiki and other distributions the audio files are usually all called alsa-base.conf
When I suggest using a modprobe option on this forum I try to use different names so I can find them again with a forum search at a later date

Thank you for the explanation, now I understand more and more how this works. My problem is I was blindly following solution online without any understanding.

I did some more digging and I ran pacmd list-cards:

Before on Discord, I was seeing Index 0 as my input for my mic which is the HDMI which I do not think I am using. So I changed in the file /etc/pulse/default.pa to be on the second profile Index 1 which has my internal mic listed under the Sources.

Now in Discord I do see the Index 1 as an option and in PulseAudio the bar is moving just above the Advanced options. Unfortunately I still do not hear the mic, but it might be something:

Also tried to reinstalling pulseaudio, but that did not do anything.

Is there a way for me to reinstall the audio drivers completely as if it was a fresh Manjaro install without actually reinstalling Manjaro?

Alright I finally figured it out. My problem was that my laptop was trying to get the microphone from the headphone jack instead of the internal mic from my laptop.

How I realised this was in PulseAudio, under the Input Devices tab I saw 2 options for the Port dropdown:

  • Internal Microphone (unplugged)
  • Headphones (Plugged In)

It was the (unplugged) part that gave me the clue that it was not detecting the internal mic.
After some research I installed this tool:

sudo pacman -S alsa-tools

Then ran this in the terminal to start it up:

hdajackretask

Finally, override the Black Mic and set it to Not Connected. Installed the boot override and restarted my computer, which then worked:

Thank you nik for your help. You made me understand a lot more about linux and now I can use Manjaro as my only OS.
