With Silverdog enabled all twitch.tv clips play without sound. The failure appears to occur when the initial video is loaded because toggling it on/off doesn't affect the behavior of a clip in an already loaded tab.
If it's relevant I had to download the sourcecode and install via Load unpacked extension because chrome refused to load the binary I downloaded from your site.

example clip (no significance other than being the one I was attempting to watch when I finally got around to investigating the problem). https://clips.twitch.tv/WittySquareRabbitAMPEnergy
