So I have had this computer for a while now and everything was working perfectly until now. My audio jack is a little broken. Its not a visible issue but when I plug my headphones in sometime it doesn't recognize it as in and sometimes the audio is lower than before. It isn't my headphones because the same headphones work in my laptop perfectly. Another thing is when I have my headphones in on League of Legends the sound is perfect but on youtube and other sounds its broken and dull. Someone please help me, thanks!
