The widget power-saving code tries to turn up/down the power of each widget in the I/O paths that are modified at each jack plug/unplug. The recent report revealed that the power activation leaves some widgets unpowered after plugging. This is because snd_hda_activate_path() turns on path->active flag at the end of the function while the path power management is done before that. Then it's regarded as if nothing is active, and the driver turns off the power. The fix is simply to set the flag at the beginning of the function, before trying to power up.
