In my game I have just learned the second word from the Unrelenting Force shout and the first word from the Whirlwind Sprint shout.
Using both of these shouts yield no sounds (also using only the first word of Unrelenting Force is silent).
I have modded my game (I also have the sound problem without mods), and it is also installed on my D: drive (so not the system or C: drive).
I read some things about moving my game to the C: drive, but I prefer to find another solution, especially to prevent any possible problems with mods/saves/etc.
Are there any other solutions?
