Fix microphone on Lenovo IdeaPad 320 on Ubuntu 18.04

Raw

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

sudo cp /etc/pulse/default.pa /etc/pulse/default.pa.bkp
#undo
#sudo cp /etc/pulse/default.pa.bkp /etc/pulse/default.pa

echo " " | sudo tee -a /etc/pulse/default.pa
echo '############################### FIX MIC FOR LENOVO 320' | sudo tee -a /etc/pulse/default.pa
echo load-module module-remap-source source_name=record_mono master=$(pacmd list-sources | grep 'name:.*input'| cut -d"<" -f2 |cut -d">" -f1) master_channel_map=front-left channel_map=mono | sudo tee -a /etc/pulse/default.pa
echo set-default-source record_mono | sudo tee -a /etc/pulse/default.pa

pulseaudio -k

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'.

Thank you so much. You helped me to use Linux again!
It works on "Mx Linux 21" on "Lenovo Ideapad 330"

aristosh commented May 16, 2023

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?

Not only Ubuntu, this also happens with Fedora.

Soloution!!!!!!!!!!!

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.
it really is silly but it works.

I hope all the problems be sovled with it.

Regards

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.
