i’m not exactly sure how, but i got my sound working on my computer! 😎
i think at least part of it is because the buttons in kubuntu 12.04.1 don’t actually look like buttons. they don’t have any clue that they can be selected, and don’t have outlines or anything that make them look like they can be selected… they just look like little icons. once i discovered that they are, in fact, buttons, i pushed one and, voilá!! my sound worked again!
unconditional victory has been achieved in the battle of the computer! 😀
