[R#201] Sound kills me and other trouble

Everytime i synch the ingame sound gets louder. It is 10% normally and goes up to 200%... it kills me...

I have a Win10 System with Asus Xonar DSX... i play NC in Window mode

I have to play NC without sound sound, atm.

In some sectors like plaza4 and pepper park1 i have loud electric noise, its like the sound of a welding equipment beeing used. That is no backgroundsound it is same volume as my steps when i move.

I play the german version of NC and the Security Chief in the Starter MC5 is talking to me in english. It is the guy for the Bot Mission.

And the Jones mission for the Soldier didn't close after the last mission completed and i've got my stuff from jones. I couldn't abort the mission. But after a relog it was gone away.
