This is not a software issue. Some jacks are built with a make-and-break setup. With that, when the plug goes in, it presses back a contact that functions as a switch for some other circuit - in this case, one that drives the onboard speaker - thus disconnecting it whil the plug is in. Apparently your new piece of hardware does not have that feature. Probably they were cheaping out by a few cents. The only fix is to replace the jack. Unfortunately it is probably built in, in such a way as to be very difficult to replace. ////jerry > > I'm out of ideas.
