I'm running Joli OS (Ubuntu based) on a Panasonic ToughBook CF-50. Everything is installed and recognized, but I'm having an issue with audio.

Audio is installed, and shows working, but can hear almost nothing from the speakers or on headphones that I plug in. It's as though its acting as a line out instead.

Everything is turned up to max in Alsamixer, I've tried removing PulseAudio, I've changed every available config in the audio panel, nothing has worked, it remains the same.

Any ideas?

Sound device is SigmaTel STAC9756,57 on Intel 92901CA-ICH3 according to Alsamixer.
