Installed ubuntu on Chromebook no audio at all

[kalpana]

Hi there, I just installed ubuntu on my chromebook, deleting chrome os. Everything works grate but the only issue is that my chromebook have no sound at all. Even connecting wired headphones the result is the same. The only way to have audio is to connect a bluetooth speaker on any kind. Since I would like the full potential of my chromebook, I would like to resolve this issue.

I tried to use this guide here https://gist.github.com/jeremy-breid...3a0ae57ed98e4a

I downloaded the asound state file and unzipped on the download folder; then I runned this 2 codes on terminal:

sudo alsa force-unload

sudo cp ~/Downloads/asound.state /var/lib/alsa

I rebooted the chromebook. There is no audio again, but i can notice that before, on the audio icon in the bottom right part of the screen, use to have a red line (like audio is no avaible), now that red line in not there anymore.

Can somebody help me solve this issue?

Thanks everybody
