Only the right side of my headphones will play on this laptop, no matter the pair of heaphones I use, so I know it's the computer and not the headphones themselves; however, putting pressure on the headphone's jack will let me hear from the left side, at least on the pair that I can actually do that with.

Is there anything I can do to fix this? I've tried disabling/enabling the Realtek Audio, messing with the sound settings, updating and restarting, cleaning out the jack...
