Wse2 its working perfectly for me after some config tries,but the voice commands still sound either like smurfs voices(high pitched) or mega slow growling voices(like a musicassete going 1/4 of its speed),didnt change or try anything at sound options cause there is not many options there.
Had this issue with both filters on and off (distance hi pass filter and the other one).
Today i asked on eu1 if someone had same issue,but only 1 guy told he heared voices that way too.
