Problem Details:Whenever i launch osu, it looks completely normal, but without any music. When i click on the osu logo to see the singleplayer/multiplayer selection screens i get horrible lag, and it's even worse in the song selection screen. I noticed that whenever i unplug the headphones i am currently using because my USB ones are RMA, osu! goes back to normal (but i can't hear sound because i don't have any headphones so i don't know if it's playing) I have absolutely no idea how this happened because i have used these headphones (3.5mm jack on front panel) the day before perfectly. Reinstalling/Resetting does not fix the problem either.
