A little POC, no interface, no switch (on/off), just an icon, launch it and it will activate and deactive speaker with the proximity sensor, I'm working on the full daemon solution with integration in settings but for now here it is: http://iktwo.wikidot.com/local--file....0.1_armel.deb please test it and give me feedback..

PD: it take a lot of time (800ms) to swith speaker on and almost no time to switch it off, I'm looking into it, but maybe there's no easy way to speed it up..
