How to fix audio from ubuntu 20.04 focal fossa "dummy-output"

Hello, I came across an issue from the latest update. I couldn't listen to any sound from my earphones it was only showing dummy-output as the default Output Device, which it was absolutely not right.

To fix it, I did the following (It must be done as root, so used sudo for it):

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

At the end of the file I added:

options snd-hda-intel dmic_detect=0

Then I did:

sudo vim /etc/modprobe.d/blacklist.conf

At the end of the file I added:

blacklist snd_soc_skl

I didn't even had to reboot, but, somehow it is always good to reboot the system after editing configuration files.

Note: I am using an acer swift laptop (intel) so please make sure that this works for you. I also use vim but it can also be done in your text editor of your preference

Happy Coding!
