Okay, my computer just ... as of a minute ago, it has no sound output. My speakers are fine, headphones are fine -- the signal is there, the audio files are fine but sound is not coming through the outlet. A few minutes ago, the sound just faded out and died. I've reset the computer several times, looked through audio output settings, etc. Don't know how to tell if it's the sound card or not. EDIT: Never mind, I fixed it. Solution's too embarrassing to describe, ha.
