Hi, Hope this is the right forum for this.... I have a Acer Aspire 5573Z laptop with Realtek HD Audio Manager for Sound. Now, here's the problem - when i Plug in the headphones - the sound still comes out of the laptop speakers i.e. both the laptop speakers and headphones work at the same time??! I have tried googling the problem but it seems like everyone else has either of the two not working. Both working seems a little odd! How do i shut the laptop speakers off when I plug in the headphones?
