D6000 audio output

[Kalvinz61]

Hello, I have a D6000 docking station connected to my laptop with windows 11. I currently have my speakers connected to the rear audio output, when I plug in headphones to the front audio port, I get audio to the headphones and the speakers at the same time. Is this how it's meant to be? Is there a way I can get the audio to stop on my speakers when I plug in headphones to the front? I can't choose audio output from windows because it sees the dock as 1 output.

Thanks!
