Dell Inspiron 7566- Audio problem

Hi, to anyone whom it may concern,

I am using the Inspiron 7566 and I saw that this laptop has a front speakers and one at the bottom. However, I am only able to access to the speaker at the bottom but not the front,can I know is there a way to have the sound come out both way (bottom and front)?

Note: When I go into Playback devices setting,I can test out the front two speaker. And when I fully turn off the "Subwoffer", I am able to hear the front speaker,but soft sound.

Thank you.
