I found the problem!
Sound Server PipeWire and Sound Server PulseAudio interfere with each other.
If they are both running (verify with command:
$ inxi -Aa) then you can disable PipeWire with command:$ systemctl --user mask --now pipewire.socket && systemctl --user stop pipewire.service
Then stereo recording works (only the left and right mic recording channels are switched.)

Thanks for your reply, but the microphone doesn't start working, when I do that.

Yes, the speakers are working fine. When I plug in a headset with microphone, then I can record from the headset microphone also. But I can't get the internal microphone to work.

Might be the jack's mic contacts aren't closing when the headset plug is withdrawn. Does the internal mic work under Windows?

The internal mic works great under Windows 10.

Search 'sound' in ubuntu gui menu. Click on 'sound settings'. Click input tab with headset disconnected. Does dummy device or built-in mic appear?

Sorry for late response, I've fallen rather ill.
Here's the info:
(I'm kind of an seasoned Unix user and am running Xubuntu currently. So you don't need to speak in noob lingua.)

(1) Does the mic work without anything else except the charger plugged into an external port?
(2) Does it still have the original factory BIOS firmware version installed?

Ad. 1) The internal mic only works under Windows 10.
Ad. 2) I stalled the latest official BIOS firmware from the Acer site.

(1) Sorry, I'm only focused on Linux mic issue. So, under Linux, does the mic work without anything else except the charger plugged into an external port?
(2) Was your only reason to update the BIOS firmware to try to fix the Linux mic problem?

Same issue in ACER Swift 3 SF315-52-50M2 (Linux Mint Tara 19 based on Ubuntu 18.04). In Windows 10 need install Realtek drivers and microfone should be work fine.

Ad (1) No the mic does not work under Linux without anything else except the charger plugged in.
Ad (2) Yes I tries the new BIOS firmware to try to fix the Linux mic problem. It made no difference. (I do intent to keep the BIOS update installed because it also fixes AGESA PI vulnerabilities.)

Open Control Panel. Search 'button'. Click 'change what the power buttons do' in left. Click 'change settings that are currently unavailable' near top of next pane. Scroll down an UNcheck box for fast startup. Save. Shut down Windows normally. Then turn it back on to boot Linux. Test mic again.

And of course there is no Control Panel in Linux… The mic drivers need to be compiled into the kernel. The developers usually get that handled with a year or so of a new laptop release.

I have fast boot off by default. So all my previous tests have already been without a hybernated Windows 10 partition.

(1) Was fastboot turned off when Ubuntu was installed?
(2) Have you tried Cinnamon 21.x?

Lack of mic input in Acer Nitro 16 has been solved upgrading Linux version to "Linux Mint 21 Vanessa".
Check your using: $ cat /etc/*-release
My current conditions:
cat /proc/asound/card*/codec* | grep Codec
Codec: Nvidia GPU a7 HDMI/DP
Codec: ATI R6xx HDMI
Codec: Realtek ALC245On previous Linux version the following driver"snd_pci_ps" was not available, now it does.
Check your with: $lspci -knn | grep Audio -A3

$sudo nano /etc/modprobe.d/alsa-base.conf
options snd-hda-intel model=alc245-acer,dell-headset-multi
#Dell is being mentioned due to similar config with Acer ones.

Hopefully helps with your issue.
