Fix microphone on Lenovo IdeaPad 320 on Ubuntu 18.04
Raw
fix_mic_lenovo320.md

In /usr/share/pulseaudio/alsa-mixer/paths/analog-input-internal-mic.conf and /usr/share/pulseaudio/alsa-mixer/paths/analog-input-mic.conf:

  • Under [Element Internal Mic Boost] set volume to zero.
  • Under [Element Int Mic Boost] set volume to zero.
  • Under [Element Mic Boost] set volume to zero

Find your source name from the following command; mine is alsa_input.pci-0000_00_1f.3.analog-stereo

  $ pacmd list-sources | grep 'name:.*input'

Edit /etc/pulse/default.pa and add the following lines, where INPUT_NAME is name of the input source from above step:

`load-module module-remap-source source_name=record_mono master=INPUT_NAME master_channel_map=front-left channel_map=mono`
`set-default-source record_mono`

Then restart PulseAudio:

  $ pulseaudio -k
  $ pulseaudio --start

mine is just empty. What should I do?

Did you open the file as a superuser or admin?

Does anyone know if this fix works for Ubuntu 20.04 LTS too? I noted some mentioned fields to have value off in this version and was not sure if it should move to zero. Besides that I also got a message saying daemon was not running when I tried to tun pacmd list-sources

Yes it does, however I had to add to the startup a command to refresh the pulseaudio to actually make it work. Now it does.

@nasatome how did you manage to get it to show up in chrome? I'm on firefox and having the same issue

Go to Settings -> Privacy and Security -> Site Settings -> Microphone -> Then select your microphone from the top drop down menu.

Thanks

This works but a week later, it reverts to the original and I had to reapply this fix again. Is there any permanent solution? Is there a bug report on Ubuntu Launchpad so I can vote? (I couldn't find it) How come Ubuntu haven't fixed this for years?

Hi, at first it worked for me. But after restart all the config got back and the microphone was not working anymore.
As I needed to install Linux Mint, I was with the same issue, and the Mint community says to install PavuControl.
Here, running Mint, worked fine and did not reseted.

Thanks! Really fixed here using Ubuntu 20.04!
Using 'volume = 0' under [Element Internal Mic Boost] and [Element Int Mic Boost], in '/usr/share/pulseaudio/alsa-mixer/paths/analog-input-internal-mic.conf' -> after reboot would start the mic with no volume, and would need to increase it with alsamixer.
Solved it by using both with 'volume = 100'.

I was just wandering around in all the forums to solve. inside canonical bug report some just said after doing the fix, just suspend the ubuntu and wake it up. i thought it is silly but gave it a shot and bingo my microphone working good as new.

This procedure worked for my Acer Aspire 5 A515-44-R2SA laptop running Xubuntu 22.04 up-to-date with these audio characteristics:
Device-1: AMD Renoir Radeon High Definition Audio driver: snd_hda_intel
Device-2: AMD Raven/Raven2/FireFlight/Renoir Audio Processor driver: N/A
Device-3: AMD Family 17h HD Audio driver: snd_hda_intel
Sound Server-1: ALSA v: k6.5.0-14-generic running: yes
Sound Server-2: PulseAudio v: 15.99.1 running: yes
Sound Server-3: PipeWire v: 0.3.48 running: yes

I suspect that a recent Ubuntu base update mangled my analog-input-internal-mic.conf file.
