Re: Audio doesn't switch between headphones and in built speaker - HP Pavillion

I am having the same problem with sound no switching to headset when plugged in.  I have an HP Elitebook 2540p serial CND1165ZLK , the HD Audi sound DeviceID is HDAUDIO\FUNC_01&_111D&DEV_7603&SUBSYS_103C7008.  Any help would be greatly appreciated,

Thanks, Tony
