UPDATE: I finally got my sound to work! All I had to do was update crouton. The following link explains how to do it: http://pastebin.com/uMJyYA4n
I replaced "raring" with "trusty" because I'm running 14.04.
In addition to this, I also reinstalled Pulseaudio and everything worked fine afterwards.
As the title suggests, I've installed Ubuntu 14.04 with XFCE on my chromebook. Sound worked initially, but after my first restart, I stopped getting any sound altogether. I have tried virtually all the workarounds found online, including installing and reinstalling pulseaudio and alsamixer.
When I try to access alsamixer via terminal, I receive the following error: "CRAS client wouldn't connect".
In addition, I'm unable to launch the audio mixer as it gives me the following error: "GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem."

This user reports an identical problem and I've seen numerous other posts reporting the same issue.
Any ideas on how to go about this?
Thank you.
