Sound stopped working - not ChromeOS update related

Ubuntu 12.04, HP Chromebook, crouton: version 1-20141118113718~master:0708c122

Hi there,
audio/sound suddenly stopped working (probably after using skype). At the same time Mozilla gets laggy. Pulseaudio/ Pulseaudio deamon reinstalled, but no sound. It's working in ChromeOS though. Chroot updated, but still no sound. CRAS seems to be fine. It might have something to do with Pulseaudio temporary files, but I am not sure. When I try to play mp3 files in VLC player I get this:

Potential PulseAudio version problem:
PulseAudio is streaming with an excessive latency. Sound may be lost or quality degraded.
To address that issue, upgrade the PulseAudio daemon to version 3.0, or disable the alternate sampling rate in its configuration

You still seem to be running an old version of the chroot. Try re-downloading the crouton installer and updating again and see if that helps.

The problem solved. I upgraded to 14.04 and that solved the audio issue.
