Microphone from external headset not recognized on Acer Aspire v5-552 with Linux Lite 5.2 Ubuntu 20.04.1 LTS

kamui · 03-03-2021, 01:10 PM

Hello!
I'm a relatively new user to Linux and I have a problem with the headset mic. It is not recognized by the OS. The headphones audio output works fine, but the microphone isn't not showing in Volume Mixer.
Can you guys, please, help me?
I tried to find on the internet some workarounds but for some of them I couldn't very well understand what I was supposed to do.
I remember that I had this problem on Windows too and I'm not sure but I think I installed a Realtek driver and then it worked. Or I had to select Headset at the prompt which appeared when I plugged in the headset.
And, please, tell me what information do I need to provide.

Without the headphones plugged in, run the command below, then plug the headphones in and use it's features, there should be some output that you can post in quote or code tags that might come in handy. Knowing the type of headphone unit might help.

Code:

journalctl -f

The headphones are called A+ Kago. It's a Romanian brand I think. And I use a jack adaptor that has 2 inputs, 1 for mic, 1 for speakers and 1 jack out mic and speaker combo.

Based on what I could find for "rtkit-daemon", it is a dependency most likely installed and used by pulseaudio. So kind of looks like it's probably ready to go since pulseaudio is involved, maybe you need to unmute them in pavucontrol or sound settings.
