Hi there, wonderful Fedora community.

I recently installed Fedora 27 on my Dell Chromebook 11 (2015 - CANDY), by first flashing a custom bios from MrChromebox.

It worked beautifully and is performing very well in most respects. However, it seems to have not recognized the sound card. When I look in the sound options it lists 'Dummy output' as the device.

The function keys don't work either but that's not a big deal, though if that can be fixed particularly for sound and screen brightness adjustments that would be great.

I'm a bit of a noob and don't really know where to start with troubleshooting these problems or what info to provide. Any help will be much appreciated!

EDIT: Can anyone give me some basic sound troubleshooting tips eg. commands to try with Pulseaudio/ALSA? I've tried some things I found online but they didn't work and/or had no result. I'm wondering if there is anything specifically Fedora I can try given that most of the stuff I find online relates to Ubuntu based distros.

Also wondering if a total reinstall of Fedora 27 is likely to recognize the sound card the second time round or if that's just a waste of time?

EDIT: if it helps aplay -l gives the following:

FYI answer on here:

The answer was:

This is normal, the sound drivers on most chromebooks aren't part of the linux kernel anymore...

You'd need to do one of 2 things to get it working most likely.

  1. Patch your kernel with the chromebook sound drivers. They can be found at the GalliumOS git repository.

  2. Switch to GalliumOS as they're kernel DOES have the chromebook sound drivers patched into the kernel.
