No Sound on Toshiba Chromebook 2

edit

Hi,

I just got a Toshiba Chromebook 2 essentially by following this guide.

During the Fedora 23 install I had to manually add a root and swap partition to get the computer booting, so that's fine, but there was one pesky thing left over once it started booting -- there's no sound. Sound works fine through the HDMI port, just not through the built-in speakers. There is a fix for Ubuntu and Arch Linux, using a modified asound.state file, found at the bottom of the webpage above.

My question is: does anyone know of a fix for this, or does anyone know where I could get started to figure out what's wrong?
