I tried searching but I couldn't find this one specifically.

When using the latest Chromium (version 37.0.2062.120 Ubuntu 14.04 (281580)) HTML5 video with audio will be out of sync. Usually, the audio plays further ahead than the video. I've tested it with YouTube HTML5 video and with loading an HTML5 video with audio directly into the browser.

It's a very noticeable difference, usually a whole second or more of latency.

I thought the problem might have been due to my audio backend, but I'd prefer not to remove Pulseaudio if at all possible.

Actually, I found this answer myself snooping around at a later date, shortly before I switched to Arch Linux.

In pavucontrol, you can head to your output device in question and select the "advanced" dropdown. There's an option labeled "Latency Offset".

For some reason, mine was set to 1000.00. Simply set it to 0.00 and the problem goes away.
