Shouts Voices are not played if Skyrim is installed on a drive other than "C:". I don't know if this already known. I really like the shout voices and i find this really annoying since my system drive is rather limited and security policies are very strict regarding user installations on C. I have verified this several times on different systems (x64, x86, win7, win8.1), with and without dlcs.
A fix would be nice.
Thanks.
