Fix No Sound and Internal Mic doesn’t Work in Linux

Hi guys. Here I want to share my experience in troubleshoting linux sound issue. The issue is no sound (ouput/input doesn’t work) and input from internal mic doesn’t work and these problems occurs after fresh install. Of course it very troubles me for my daily usage with Linux.

NB : This was happened to me when I’m using Parrot OS 5.1 in Acer Aspire 5 (11th gen of i5 CPU). I’m not sure wheter this tutorial can work on other distribution, but you can try it :D

For easier, Firstly, install pavucontrol to manage audio :

sudo apt update && sudo apt install pavucontrol

Then, create alsa configuration :

sudo nano /etc/modprobe.d/alsa-base.conf

Then write the following lines in it :

options snd-intel-dspcfg.dsp_driver=1

options snd-hda-intel model=laptop-amic enable=yes

Like shown below,

Save it with Ctrl+x then type ‘y’

And install sof firmware :

sudo apt install firmware-sof-signed

Then reboot your system.

It works for me after rebooting.

NB : Make sure you set correct setting for audio, check it with pulse audio control (Pavucontrol). Thank you…
