No Sound on my Samsung NP950QED Laptop Speakers

[Thierry Marchisio]

Hello,

Yesterday I have installed Ubuntu 23.10 on my laptop Samsung Galaxy Book2 Pro NP950QED for the first time.
I never heard any sound from my laptop since the installation of Ubuntu. It worked with Microsoft Windows.

I spent the whole day on many forums, alsa-project.org... Nothing worked yet.
Every time I try a new configuration, I test both left and right speakers in the Settings application.

You can find my Ubuntu Alsa configuration in the file attached generared by alsa-info.sh

Thank you for your help !
