User blog comment:Harbumz/Introducing Vignette, Wikia's New Thumbnailer/@comment-1820055-20150329200823

I just want to let you know that this will break the audio player for some popular gaming wikis such as leagueoflegends (source), elderscrolls, kancolle, and a few other small wikis that use sm2.js. I know this is out of bounds of wikia support, but maybe there's a compromise for this predicament, or a small thing we missed that could fix the player that we do not know of.

See this sandbox page for comparison of vignette vs old CDN. Audio players which links to vignette ogg files open in a new tab, while those that use the old CDN,  works just fine. (To see CDN links used for each player, use browser devtools to inspect element)
