Ohh btw, 1.0.18a connects the hardwar beeper, which can only be disabled 
at compile time, just as a suggestion, isn't there any way to create a 
way to mute this on runtime? For advanced users like us this is no 
trouble, but for newbies this is an issue, and might scare them, the 
beep on a dell laptop is quite annoying (you can't image how annoying 
it's comming out of the headphones)
