You have two different sound devices in operation here, the onboard Realtek and the offboard UA4.

ASIO4ALL can address either one and you have to go into the ASIO4ALL Control Panel and tell it which one you want it to use. That would be the one that is hooked to your monitoring speakers at the time.

Tu further confuse the issue, the UA4 likely has native ASIO drivers of its own, too.
