Comment 55 for bug 1784485

Thanks to craig-jackson if you want to check before compiling your kernel if you have the same problem that I had, you can check if the sound can work for a few seconds with the command below :

sudo apt install git
git clone https://github.com/VanVan/check_sound.git
sudo ./check_sound/check_sound

If you can hear a sound from your internal speaker it's good, if not, compiling a new kernel can still give you sound, depends on your laptop.

When you compile a new kernel, do not forget do to a git pull inside the linux folder or you can remove and clone again the repository to have the latest commit (hda_codec.h correction):
git clone https://github.com/VanVan/linux.git
