That sounds like a bug with the ALSA drivers not correctly sensing the state of the jack at boot time. Fortunately, the fact that a plug/unplug fixes it means that the signal routing (what pin of the sound chip connects where) is correct. You probably want to post at alsa-devel@xxxxxxxxxxxxxxxx and explain *in detail* the problem - include stuff like your exact kernel release, the laptop model, the sound chip used (probably listed in 'lspci' output), and so on.
