Use AudioDeviceTypeAddr when setting device for effects.

Separate SET_DEVICE and SET_INPUT_DEVICE command in effects as it can
be multiple devices for output case, but only single device for input
case.
Use AudioDeviceTypeAddr instead of just audio device type as address
can be useful to identify audio device if there are multiple devices
with the same device type connected.
