Because I live in a house with other people, I need to listen to music with headphones on. However, the left earphone unexpectedly stopped working (whilst the right still works perfectly). How do I set the output to mono so that I can properly listen to music?
EDIT: I know only the right earphone will work, but I still only hear part of the music (the part that would have normally gone only to the left earphone doesn't go to the right, even if the left is broken).
