I've never used a gui to configure sound. It doesn't look muted in alsamixer. This system is a laptop and the output goes either out the onboard speakers, or most of the time headphones connected to the on board jack. And on of the first things I checked was whether I wasn't hearing sound because of a funny stream, etc, so I loaded up audacious and played a couple of MP3s to see the output. Still no sound. I'm so totally confused by this. I don't recall a recent alsa update, and I know the hardware is okay (at least it seems to be) since my system dual boots to XP and I get great sound from it.
