this is the first time I am posting here but I am kind of desperate.
I don't have any more sound on my laptop, only "Dummy output" whereas it was working fine yesterday. I tried several methods, uninstalling and reinstalling alsa and pulseaudio then force reload, stop win10 from hibernating, literally everything I could find on the internet. Here are some unsuccessful solutions I tried :
- No sound on Ubuntu 18.04
- Ubuntu 18.04.1 LTS, Dummy output, no sound
- https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html
- No sound in Ubuntu 18.04 HP notebook
I have a dual boot Win10/Ubuntu 18.04. Here are some information that could be useful for you :

alexis@hp-envy:~$ pulseaudio

If you have any idea of a process to find more information about what is wrong and/or how I could fix this, please help me. Thank you !
