Lenovo ThinkPad T14s Low Microphone Volume

Hello,

The volume of my built-in microphone on my ThinkPad T14s (Gen 1, AMD) is really low. I have tried boosting the audio using pulse audio but that did not work. I think it is a driver related issue since it works perfectly fine using Windows 10.

I am using Manjaro 21.1.2 GNOME, with kernel Linux 5.13.13-1-MANJARO.

What should I do to make this better?

Thank you in advance!

I have the exact same notebook and I can confirm the low mic volume. Nevertheless, I had so far no complaints about it from my meeting partners. My mic volume setting is 100%.

I had complaints from my meeting partners, Zoom even filters out the microphone sound as background noise which makes it look as if I am muted.

:+1: Welcome to Manjaro! :+1:

  1. Please read this:
    How to provide good information
    and press the three dots below your post and press the :pencil2: to give us more information so we can see what’s really going on.
    Now we know the symptom of the disease, but we need some more probing to know where the origin lies… :grin:
  2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
    Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.

:+1:

P.S. If you want to notify me that you did provide this information, please :heart: this message and I’ll come back and have another look.
P.P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you’re using, which exact CPU/GPU or Kernel, … you have without typing it every time

That doesn’t mean anything: Vendors just configure the Microsoft driver settings optimally for their hardware whereas you’re probably stuck with the defaults for the hardware under Linux.

  1. You have both PipeWire and PulseAudio running so let’s start with disabling PipeWire to keep things simple:

    systemctl --user disable --now pipewire.socket && systemctl --user disable --now pipewire.service && systemctl --user mask pipewire.socket
    
  2. Execute:

    alsamixer
    
  3. Press F4 to go to the capture settings

  4. Press F6 to select the default:0 and you should see something like this:

    image

  5. Use the on your keyboard to select the capture modes you have one by one.

  6. Use on your keyboard to crank everything up to 50% if it’s lower than that and 90% if it’s already above 50%.

  7. Go back to 5 and take the next capture mode until done.

  8. Press Esc to leave alsamixer

  9. Whisper during the first zoom meeting to ensure you don’t blast everyone’s ears out!

  10. Use your normal microphone settings in Gnome / Zoom Microphone settings to bring the microphone down to an acceptable level for your meeting partners.

:crossed_fingers:

Thank you for the instructions, I disabled PipeWire with the given command.

I had the following windows in alsamixer:

These are all my displayed devices:

default 0:

default 1:

Performing the Mic boost does not really change anything in my experience. The capture level was already on 100%. The USB device is a crappy webcam Mic which I do not use for anything.

PulseAudio settings:

  1. Please execute:

    alsa-info.sh
    
  2. Answer Y

  3. post the link you’ve been given to the data you collected or post the full contents of the /tmp/asla-info.txt.RandomNumber file if you feel hesitant to upload your data there.

  4. I will then call in our resident Audio Über-Guru. :grin:

:crossed_fingers:

Thanks for the help, I really appreciate it!

Have I told you to try an LTS kernal already???

If not, please read this:

While I analyze your alsa output.

:bowing_man:

I did not try that yet, but that is something for the weekend since this is my main device to do my work

Okay, I tried out Kernel 5.10.61.1 LTS and that did not solve the issue sadly…

@nikgnomic

Low mic. Boost doesn’t help. I’m out of my league.

:sob:

Did you try this already?
https://wiki.archlinux.org/title/Lenovo_ThinkPad_T14s_(AMD)_Gen_1#Microphone

Microphone

The microphone may not be operational. A possible fix is to blacklist the snd_pci_acp3x module (to allow newer kernels to use snd_rn_pci_acp3x?) 

Not that it’s not working, but maybe it makes a difference… :man_shrugging: (I have a similar laptop; never tried the internal mic though)

Yes I tried that again, does not seem to make any difference
