Hello there,
I’m kind of blocked with my audio, that is just saying : Dummy output. I just installed Manjaro GNOME and I’m a bit frustated with the audio… I checked other post, but I don’t know if their problems are the same as mine…
Newbie here so can you be precise in what do you want exactly please…
Thanks for your help
Hello and welcome to Manjaro forum.
I know that the people here that can help will ask for your inxi Fazy from terminal
https://forum.manjaro.org/t/how-to-provide-good-information/874/9
I personally had Dummy output problem on my laptop which was resolved by updating BIOS.
There is the output from inxi -Fazy :

And I have also an other problem, but it will be in an other post (graphic driver) and I have to look other post for this graphic problem…
And thanks for your help, i will check my manufacturer’s recommendations for bios update.
Update : After bios update, still have dummy output 
Resolved
Install sof-firmware from the package manager (pamac I think), google it 
and then I just follow this guide solution
