Media volume auto lowers when you plug in headphones. Raise it back up. Alternatives, get over ear headphones, or decent I ear headphones. I suggest something with 40-60mm drivers for over ear, higher driver size=louder sound. I can't suggest in ear as I don't use in ear. Get an amp? Fio-e3 is a decently cheap one that definitely boost your sound volume of overear headphones . about 30 percent. (in ear will only distort with such a cheap amp.) or better yet do my "bus combo" (a pair of skull candy hesh ones, sound isn't where I'd want it,-the base is muddy, highs are over hyped and mids are none existent but it does get extra loud with the e3 plugged in, I slapped on an e6 amp and the headphones get sometimes physically painful to listen too)
