Public bug reported: I have an old Toshiba Tecra A5 laptop that I recently installed Ubuntu 12.10 on. The laptop has internal speakers left and right, a hardware volume control, and a headphone jack. I am able to play audio successfully through the headphone jack, and control the volume with the hardware volume control, but I am not able to play back audio through the internal speakers.
I've checked the alsa mixer and the system Sounds panel to confirm that all volume controls are up, not muted, and have tested playback on all audio devices. Playback on headphones works, but playback on internal speakers does not. I'm filing a bug report per inrtsuctions in this related bugreport: https://bugs.launchpad.net/ubuntu/+bug/783582 Extensive logs should be attached by the "ubuntu-bug" program.
