I've never had any problems with any other voice and whirlwind sprint works fine for me.<snip>
But i have tried all shouts and i found 3 with issues.(including dragonborn and dawnguard)
Fire breath: Yol have sound , Yol Toor, only Toor have sound , Yol Toor Shul nothing.
Frost breath: nothing.
Soul tear: nothing.
Any other voice in game seems to work correctly.
I checked in my game by using the console to obtain the Fire and Frost Breath shouts and Soul Tear. The voices for those shouts do not play so I going to assume this is happening to everyone.
I can't give a definitive answer as to why this is happening, if I knew then I would have fixed this by now. As soon as I find out the cause I'll upload a fix or, if not fixable, inform everyone of the situation.
