You can try looking at your volume mixer (right click the volume icon on your system tray and open volume mixer) and see if one of the sliders is low. You mentioned app, are you using youtube app? Or are you using a browser? In any case, did you try a different browser, or if you are using the app, any browser? You can also try enhancer for youtube extension (available for firefox, chrome, and edge) that has a built in volume booster functionality. That's all I can think of right now. Let me know how it goes.
