First Controller, Troubleshooting Audio

I recently bought my first DJ controller, I’m really new to all of this but comfortable enough when it comes to using computers. I bought myself the DDJ Rev 5 Controller and have it setup with my MSI Thin gaming laptop. I’m using all the provided cables but cannot get audio to play on my headphones. My headphones are Pioneer DJ HDJ-X7 so I’m sure it’s not an issue of the headphones. When I test the sound on my laptop I can hear audio through the headphones. However, when trying to hear the tracks on Serato I can’t hear anything. Everything is up to date, I’ve messed with all the knobs to ensure nothing was turned down, tried turning the computer and controller off and on multiple times and still can’t seem to hear any audio. I tried researching online and on Reddit but haven’t found an answer. By any chance does anyone know what I could be missing or any tips and advice that could help guide me in the right direction? I appreciate any help I receive! :)
