I've been trying to fix this alone for two days now, searching just about every forum, subreddit, and Google search result I can find and nothing has fixed this (at least permanently). http://skyrim.nexusmods.com/mods/456 and http://skyrim.nexusmods.com/mods/896 did NOT work and the 'sixchange' command reverts to the bugged state on loading the save.
I am also very open to just replacing the sound file but haven't the faintest which file it is, I did install http://skyrim.nexusmods.com/mods/19333and while the sound itself it very similar to the fire replacements included in that mod removing the files does not seem to change how it sounds leading me to believe it is linked to spells or dreugh shouts.
And here's the mod list.
