You are not alone- with low sound on laptops- simple install this free program and AMP it up! after installation make voicemeeter your default in speakers... on the program itself make A1 hardware output as your laptop speakers, slide the bar all the way up, and it will make everything louder! But you must always keep it running and minimized for it to work.
