Took a while for the issue to reappear. The length of time that it occurs is random. I've been able to watch an entire movie without issue. Other times it won't last a song. Once it occurs, I have to open the sound control, switch to stereo and back to 5.1. The issue is program agnostic (vmware, chrome, rythmbox, system sounds). Killing pulseaudio (https://wiki.ubuntu.com/PulseAudio/Log) fixed the corrupted audio as well.
