Galaxy book flex internal speaker not working

Hi everyone,
I would like to ask support in troubleshooting audio.
I installed manjaro GNOME on a Samsung Galaxy Book Flex, everything is working fine including the S pen!

Problem
The only problem is about audio, in particular from internal speakers; bluetooth headphones (Galaxy Buds Pro) work fine.
I tried:

  • reproduction of youtube videos on google chrome and on firefox
  • speaker-test command
  • gnome settings test

Speakers are not working in all mentioned cases.
Built-in microphone is working!!

System info
I try to attach all you need to reason on the problem.

What I tried to solve the problem
Trying to solve the problem I followed the guide: how to set up the audio card in samsung galaxy book (forum is not allowing me to share the url) in this forum, but speakers are still not working.
Actually I was not able to follow all the steps in the guide, because the alsa-base file, mentioned in step 6, does not exist.
I tried to further search on the forum, but all the post I found proposed solutions already involved in the previously linked guide.
alsamixer
On alsamixer sof-hda-dsp is available as audio card and after selecting it I raised all the volumes, but still no sound.
I hope that what I provided is enough for you to give some suggestions.
Thanks in advance!!

Having the exact same issue on exact same system running Linux Mint. Hoping something comes out of this.
