I highly recommend to install it manually. Mod is not working? Did u install it manually?

My favourite version. Little less saping while swinging your sword, but there is some

So you're so fit, ya?
You will not make any voice while swinging your weapon

Now your power attacks will be silent. If you want toned or completely silent swinging install them first and overwrite by this. Note it doesn't contain low stamina option (exhaustion)

You will not make noises while power bash and fully successful (0 damage taken) block should be silent too
Sorry for another esp on your list

In low stamina case, your power attacks will sound the same as in full stamina.
Future plans: add heavy breathing. More future plans: find special sounds for low stamina situation
For now I recommend "exhaustion" mod

In low stamina case, your power attacks will be quiet (see hotfix video)

You're a tough guy, no pain!

So your character is very fit teenager?
Silent swinging with vanilla power attacks
