Sorry, let me clarify. The jack cannot tell the difference between 
headphones and speakers. I'm just saying that they should not be treated 
the same, because headphones and externally powered speakers should have 
different output levels, impedance etc, for optimal quality.

So, in theory we should have one button for headphones and one button 
for speakers, but because we currently do not support the line out mode 
at driver level (which is the optimal one for externally powered 
devices), I think it's better to leave speakers completely for now.
