Serato DJ Pro/Lite using laptop speakers mistakenly routing audio to the controller's headphone port

Hello, I'm currently playing the "Use laptop speakers" option on Serato DJ Pro and it's working all right, I can hear the master audio on my laptop. The problem is that I can also hear the master audio on the headphone port of the controller (DJ Control Inpulse 200) even when when the master and both headphone buttons are turned off on the controller. If I press turn on the master to listen on headphones, the audio just gets louder. The audio on the headphones is also slightly out of sync with the laptop speakers, like I'm playing via Bluetooth or something. I tried with another controller (the same model but MK2 version) and the problem persists. It also happens with Serato DJ Lite. I'm on Windows 11.
