I was going to play osu!, whenever randomly it says that I don't have a valid audio device plugged in... but I do. I have my Realtek High Definition Audio speakers plugged in, which have a separate plug that I have my earbuds plugged into. (To put into more simple context, I have earbuds for audio. For some reason it still won't let me, and it doesn't give me any options besides default: http://prntscr.com/jxsyd6. I'm not sure how to resolve this.
