Windows freezing on volume change

Hi @ All I have some problems with my Synapse and i cant figure out what happens with my Windows 10 when i change volume. First of, i need 2xSynapse installed... and yea thats something that maybe is the main problem. Synapse 2 for my old Kraken headset and Synapse 3 for my Black Widow Chroma and Mamba Elite Chroma. My problem currently is a slow down to a under 1 Fps (until freeze) of windows for a couple of seconds when i change the volume. The crazy part is that the mouse cursor works fine, only windows freeze. In Games i dont have any problems at all on volume change. Only thing i see in the task manager is a 15% CPU useage on the Synapse 2 and 15% on Desktop Window Manager. After some seconds of freeze it runs normal again and the CPU useage goes down to 1-2 % Reinstall didnt do anything and yea Synapse 2 is the problem because if i close it, everything works fine. And no i cant just use Synapse 2 for my Keyboard and Mouse because it doesnt detect them. Why did Razer not include thier own headsets in the new Razer Software? Does someone had this problem? Exist a workaround?
