OK, I'm a newbie here and I just purchased an Allen & Heath XB-10 USB mixer. I connected the USB cable to my computer and the other end to the mixer. However, when I connect the USB cable, my computer speakers won't play and I have to listen to everything through the headphones from the mixer. I have new speaker monitors coming soon, but I would still like to use my computer speakers for my computer. Is there a way I can do this? Or will I have to use my monitor speakers for everything and will the monitors (Adam A3X) work with my computer?

Thanks
