Then imho it must be some obscure alsa mixer setting that is setup in the wrong way in the real system but right in the live one. Had this problem once with my internal sound card which might indicate that live ubuntus tend to so the alsa mice differently to real ones. After ask jack accesses the sound card using alsa but cannot know about every single setting a hardware manufacturer or the person coding a driver may think of. But alsamixer most probably will.
In my case I searched for a long time since the microphone mute button was labeled wrong. But perhaps the same pin of the same chip can be wired to different functions on different systems.
