Yes if your DAC is connected via USB to your laptop.
Otherwise you will need to connect the DAC to something else (a streamer) which will then receive the music (via wifi or ethernet) and pass it through your DAC (I don’t believe your DAC has a streamer built in).
You should be able to scroll up on this screen… there should be at the top of the screen page a title ‘Audio’ and under it a section ‘Connected to Core’ or something similar. Under this section you would find the output ports of your Windows laptop, typically USB and HDMI.
Sorry, I didn’t get that you run the core on your NAS. So, in order to output to a DAC connected to your Windows laptop you would need to install Roon on your laptop, too. You would really only need the Roon Bridge component to output sound on your laptop, but can also use the full Roon package to use the interface from your laptop.
If your laptop is really connected to the same network as your core with Roon installed on it, the Core should see it and expose its digital interfaces (USB, HDMI). For the USB interfaces to show up the USB DAC needs to be connected and powered on.
Is this all so in your environment?
Could it be that Windows firewall is blocking Roon on your laptop? Could you temporarily turn off any firewall and/or antivirus software on your laptop to check…
