Wrye Bash - strange sounds?

[Calaiope]

Hello, 

I am new at trying and experimenting with wrye bash. Everything is fine so far except for some strange sounds. It happens with the bashed.patch installed when i turn off the night vision or when I do a one hit kill or a sneak attack. It is pretty anoying and I am looking for a way to turn it off or using vanilla sounds again. 

I did read a lot in variosus forums but couldn't find a similar topic/problem so I will try it here  Any ideas what that could be?

Thanks in advanced.
