External Microphones not detected Linux Mint 20.1

[eef4de]

I updated my OS to the latest version as of this post. The headphones work on plug, but only the earphones. The mic isn't working. As for the mic I just bought, it also wasn't working.

I looked at the sound settings and went to output. There only appeared the built-in microphone. I tried plugging and unplugging my mic but it was not detected. Based from the test sound, it only detects the sound from my laptop's built-in mic.

When I open audacity, there also wasn't a selection of the speakers I should have.

I searched for ways to do it online but so far, I only saw stuff related to the Sound settings that I mentioned before.

I tried following this:

Thanks to the forums.
My USB microfone working fine after the below changes to the file /usr/share/cinnamon/cinnamon-settings/modules/cs_sound.py
self.inputSelector = self.buildDeviceSelect("output", self.inputDeviceList) # the line with bug
self.inputSelector = self.buildDeviceSelect("input", self.inputDeviceList) #correct changes

Tested with Microsoft webcam & SENNHEISER headset

But it still didn't work when I tested in in input sounds.

Hello, same problem here.

headphone and mic (jack), which is correctly working under Ubuntu on another computer.

On this laptop (only one jack) with Mint cinnamon 20.1 fresh install, the headphone is not detected at all.
I installed pavucontrol -> it detects the headphone and mic. I selected it for input and output. Output works, mic doesn't.

Here are some of he other things that I tried:

Code: Select all

pacmd set-default-source alsa_input.pci-0000_00_0e.0.analog-stereo

But I got:

Code: Select all

Source alsa_input.pci-0000_00_0e.0.analog-stereo does not exist.

I also installed PulseAudio Volume Control

Code: Select all

flatpak install flathub org.pulseaudio.pavucontrol

Then run it

Code: Select all

flatpak run org.pulseaudio.pavucontrol

And I got

Code: Select all

Gtk-Message: 08:44:46.552: Failed to load module "xapp-gtk3-module"

Basically what appeared is just the same as that appears in Sound > Input from the local settings. The mic from my headphones where not detected.

Then I also run this to see what happens despite not knowing what this does:

Code: Select all

sudo fuser -v /dev/snd/*

I got:

Code: Select all

                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  user      1351 F.... pulseaudio
/dev/snd/controlC1:  user      1351 F.... pulseaudio
/dev/snd/pcmC0D0c:   user      1351 F...m pulseaudio
/dev/snd/pcmC0D0p:   user      1351 F...m pulseaudio

And yep headphone mic is still not working.

[mohican]

Hi, I checked the cs_sound.py file : it is correct.

In Pavucontrol, nothing new. I can select between internal mic and headset mic ("unplugged"). But the headset mic doesn't work (the output works when selecting headset).

I also tried alsamixer, put to 100% one if the input bar that was empty, but this did nothing.

[mohican]

So in conclusion, I have a headset that does work on Ubuntu on a desktop,
and doesn't work on Mint on a laptop.
Strange, isn't it ?
