Audio sounds flat through headphones. No bass only through this computer.

The bass in my headphones seem to have completely vanished out of the blue. My music producer brain went crazy trying to figure out what I did wrong in the DAW and when I learned it wasn't just the DAW I panicked. I tested on YouTube videos and all that. I've checked my audio equalizer and the Bang & Olufsen app yet there seems to be no problem coming from there. I've tested my headphones on other devices including a different HP computer of the same model and the bass works fine there. I'm wondering if it might be a driver problem. I'm hoping someone could give me a reliable source for getting new audio drivers and properly installing them. I apologize if this is a stupid question. I'm stuck and have no way to figure all this out.
