Because of this?
Yes I had to shutdown the computer, open it, remove the battery, put it in charge so I can power it on, power it on, type a command, shutdown it, put the battery back to remove the Write Protection of the Chromebook.
But that's not all ! I had also to launch a script of https://mrchromebox.tech/ for installing SeaBIOS instead of the Chromebook's BIOS that could only boot on ChromeOS .
Not everyone has knowledge of Chromebook's,, Myself being one,, & as you see you have ONE main website that offers help with chromebooks ( Mr chromebox ) ,,,
What is the model/brand of this chromebook?
Acer Chromebook 314
Ty ,
Did you follow an above suggestion to follow this link,?
Dont just click the down arrow, please click the link & go through the instructions.
Let us know how you go.
Hi
I followed that : [HOW TO] Fix audio not working
and Chromebook "no sound" fix for Ubuntu · GitHub and both didn't worked unfortunately
Sorry for the delay as my internet is very poor at this moment.
Ok can you try running these commands.
sudo ubuntu-drivers autoinstall
sudo apt install ubuntu-restricted-extras
reboot
Then retry you sound,
Are you able to open pulseaudio? or Alsamixer?
Note: as you have more knowledge than myself with chromebook/BIOS,, Please visit Mr chromeBox
& check if coreBIOS is more suited than seaBIOS?
I still think you may need to get a 4-8g usb stick to preform the installation,
Hi
Unfortunately it didn't work for me : pulseaudio still says the audio output is dummy.
I don't think the BIOS is the problem because the sound worked on many others distro.
Please show us the output from this command.
sudo dmesg | grep audio
If using the DA7219 audio chip, Please try looking on Acer website for audio drivers to suit.

There is no driver for my Chromebook as I understood :
Did you check the link?
Ahhhhh thanks I didn't see that
Unexpected, maybe. You won't see that in a Windows error report.
IT WORKED ! Thanks you two guys !
Linux is awesome
The micro still doesn't work but it's already awesome that the sound works
Double check alsamixer when you get a chance. It is notorious that changing the drivers reverts alsa to default settings.
That's good advice.
Once you have made setting changes in alsamixer
make sure they are saved using:
sudo alsactl store
Hi it doesn't seem working.
The micro input is a monitor, is it normal ?
Does this show as Front Microphone in Alsa?
In the Input tab on sound settings, does it show as provided by your Graphics Card?
