Ubuntu 20.04 does not recognize headset microphone

Question

I have an Acer E5-574-307M notebook and I have Ubuntu 20.04 installed but it cannot recognize my headset microphone (Xiaomi Piston 3).

I searched the internet and found these possible solutions:

1. Edit the file /etc/modprobe.d/alsa-base.conf and add this command to the last line: options snd-hda-intel model=dell-headset-multi. However, it didn't work!

2. rm -rf ~/.config/pulse/ and then restart the pc. However, it didn't work!

3. Use cat /proc/asound/card0/codec# | grep Codec to find out what the audio codec is and enter in this website to find out what the configuration is (alc255-acer, in my case). After knowing the configuration, enter the command: options snd-hda-intel model=alc255-acer in the file: /etc/modprobe.d/alsa-base.conf and restart the PC. However, it didn't work!

P.S: This notebook only has one P2 input for the phone and microphone.

Answer 1

This question is possible to duplicate of the question from here -> Headset microphone not working on Ubuntu 20.04 If not, try these steps:

• Go to https://superuser.com/questions/1312970/headset-microphone-not-detected-by-pulse-und-alsa and try the steps mentioned in the first/second answer.
• Try installing multimedia extras plugin: sudo apt install ubuntu-restricted-extras If problem persists, try reinstalling PulseAudio and other audio drivers I hope this solved your problem.

Answer 2

You need to add the following commands in /etc/modprobe.d/alsa-base.conf.

options snd-hda-intel model=alc255-acer
options snd-hda-intel dmic_detect=0

Now, reboot.

This will disable the internal mic and detect the external headset mic.

This worked on Acer Aspire 5 A514-54.

Answer 3

I had the same issue in my lenovo ideapad 135

I have added below lines to /etc/modprobe.d/alsa-base.conf

 options snd-hda-intel model=headset-mode  
 options snd-hda-intel model=dell-headset-multi

Reboot your system once after adding above lines
