Good. You may need to assign the physical optical input you use to a "logical" receiver input (e.g. TV, DVD, etc.) in the receiver's settings, or at least check what it is already assigned to so that you can select a proper input for listening. There are other things you can look into for improving the SQ such as using WASAPI or ASIO for playback, but even setting the DDC as the default audio device in Windows should be a big improvement over using the 3.5mm audio out from your laptop.
