Public bug reported:

On a Samsung Chromebook 5 running Ubuntu/saucy, the audio does not work
at all.  I found two things on the Debian wiki that made it work for me:

https://wiki.debian.org/InstallingDebianOn/Samsung/ARMChromebook

(In Ubuntu, I've mounted the ChromeOS system on /media/root-a.)

 1. copy some alsa support files from Chrome: 
     cp /media/root-a/usr/share/alsa/ucm/DAISY-I2S/HiFi.conf 
/usr/share/alsa/ucm/DAISY-I2S/
 2. edit /etc/pulse/default.pa to add this line: 
     load-module module-alsa-sink device=sysdefault

Then I rebooted and I had working audio!  It would be great if this
could be included by default!  This laptop runs XUbuntu quite nicely,
and costs US$250!

 /media/root-a/usr/share/alsa/ucm/DAISY-I2S/HiFi.conf is attached.
