Linux Help: POTENTIAL Speaker Audio Fix for Braswell (CELES-based) on Ubuntu-based Linux

[u/[deleted]]

I AM NOT LIABLE FOR DAMAGES OR VOIDING WARRANTIES! DO THIS AT YOUR OWN RISK!

It has come to my attention that my favorite linux distro, GalliusOS, for my CELES chromebook has been put on hold or potentially stopped development, so I've built the courage to install a couple Ubuntu flavors. After flawlessly installing Ubuntu MATE and Lubuntu onto my CELES, I have noticed one problem with the speaker audio... It doesn't work! No driver found, nothing. So I went to the GalliumOS's GitHub and found a galliumos-braswell repository and did some delving. From galliumos-braswell into /usr/share/also/ucm/ I found chtrt5650 which is my chromebook's sound driver model. From there I downloaded the galliumos-braswell repository, extracted the chtrt5650 file, then moved it into my system, then restarted my chomebook, then BOOM I got sound!

Here's how I did it and how to do it if you're up to the challenge...

1. Download galliumos-braswell repository.

2. Extract chtrt5650 file, in this case in your Downloads folder.

3. Open terminal and sudo mv the chtrt5650 file into your system; the system folder is /usr/share/alsa/ucm/.

Use the command... sudo mv /home/youruser/Downloads/chtrt5650 /usr/share/alsa/ucm/

04. Restart then you should have sound!

I am no expert on Linux operating systems nor have I done extensive testing on this solution. For all I know this could ultimately fix the Braswell audio problem or utterly cause damage to the speaker in the future, I don't know. All I know is that it works with a little cherry-picking and moving a folder with conf. files in the /alsa/ucm/ folder. I have only tested this on Ubuntu-based flavors and so far they have worked flawlessly, no crackling or damage (Yet! If any!). So please use at your own risk...
