Public bug reported: I observe a somewhat buggy behavior in comparison to 11.10. I have a desktop PC with audio out on the back (I use it for speakers) and audio out in the front (used for headphones). I have both: speakers and headphones connected all the time. In 11.10 it used to provide output to both, so I just switched the speakers off when I wanted to use the headphones.
No the behavior is as follows: 1. Boot Ubuntu 12.04 with speakers and headphones plugged in. Result: Audio only on headphones 2. Unplug headphones. Result: No audio heard at all. 3. Unplug and plug speakers. Result: No audio heard at all. 4. Plug headphones. Result: Audio only on headphones. 5. Suspend to RAM and wake computer. Result: Audio on both: speakers and headphones. 6. Unplug headphones and reboot. Result: Audio on speakers. 7. Plug the headphones Result: Audio on both: speakers and headphones. The bottom line is: if I want to have sound on speakers I need to either boot Ubuntu with headphones unplugged or boot normally (with both speakers and headphones plugged in) and perform suspend-to-ram and wake procedure.
