In my case it does even disable all the sound from my computer. After reinstalling my computr is completely quiet both in on board card and on KB37. Unpluging KB37 doesnt start onboard sound. Windows say sound has been disabled, When i check in control panel it says both onboard card and KB37 are set to "standard" even it both ar disabled. This is catch 22. And I have a soundtrack to make to a video......
