Same problem, is there a way to fix it?

Do you also have Way Of the Voice?

i have the same problem

Yeah I'm having this problem as well. @aberation, if you see this, could you fix it?

I know this has nothing to do this with this post but do any of you have aby idea where you find the jedi because I cant seem to find him

I am having double sound as well

I found that when I say, equip a 1h lightsaber to my left hand, and an iron sword to my right, the sound doesn't play twice. Yet if I switch hands, it plays twice, as if the game thinks that since I am dual wielding, I have to be using two lightsabers.

Long story short, using the lightsaber in the left is a pseudo fix.

I started having the problem immediately after downloading the Unique Magicka Sabers mod. Disabling it fixed this. I dont know if any of you have more than 1 lightsaber-type mod, but you might want to try disabling one if you do (if feasable).
I would like to be able to use this other mod, so if any of you have a better fix, it would be appreciated.
