We're sorry to hear about this. The SVF15416STW is a non-US model thus we have limited information about this model. Please make sure that this model is compatible with Windows 10 operating system. If it does, check weather there is a new driver for the microphone. If the unit is not compatible Windows 10 then more likely it is the limitation of the system.
