So that's what it is. I plug em in, and it still comes out the speakers. Happens with any pair.I've re installed the driver but nothing. I have an Acer aspire 5770. What shall i do?

Yeah I am. It has the picture of headphones above it :(

Okay i reinstalled the driver both ways. didnt work.

I think it is probable that the "switching system" in the actual socket, is either bent or broken. It is only a thin piece of steel connected to a contact.

That would depend on your experience of testing and repairing of electronic devices!

Your Acer Aspire is worth less than $568 and for that money you can buy a very good brand new laptop. Take the one on this page as an example http://officedepot.shoplocal.c.....edepot.com

Before you do anything dramatic: Have you tried to mute the speakers? Does that mute the headphones too? But no way should you be spending over $500 for such a nit; maybe you find a friend who knows how to take a laptop apart - it is not obvious.
