No sound on Xubuntu 14.04 on Acer C720

I installed an Xubuntu 14.04 image from HugeGreenBug and my audio stopped working after I rebooted during an upgrade a few hours after installation. I've looked at posts about this here and tried deleting my PulseAudio configuration, uninstalling alsa and pulse audio, restarting alsa, etc.

The problem started after I rebooted while updating packages, and VLC uninstallled itself. Audio was working at that point, but quit after reinstalling VLC and rebooting. Here is my alsa info script output.

I was able to get system sound working by adding my UID to the audio group. I still am not getting audio in Chrome however, but that might just be a bug in Chrome at the moment, as was suggested here.

If anyone has any more Chrome specific suggestions, those would still be greatly appreciated.

Please make sure that the file /etc/modules contains:

chromeos_laptop
i2c-designware-core
i2c-designware-pci
i2c-designware-platform

If not, manually update it and then try rebooting the machine.
