a recent development, but whenever i plug headphones/speaker cable into the headphone socket on the front of my laptop, sound comes fine out of my headphones, but the speakers don't cut out. which is ok if i just want better headphoney sound, but not so great for privacy, or use in public places where slightly tinny speakers can be annoying for all involved.
running XP sp3, no major changes to software or hardware prior to the problem emerging.
any precedent/help to be had?
