I have searched alot on multiple forums regarding this! Its hard to believe that nobody has a credible solution to this simple problem!!
I have dell inspiron N4030 and when i plug in headphone in the stereo jack , sound keeps on playing from both speakers and independent headphones at the same time!! This really is annoying! I have tried refreshing the driver software , have installed IDT HD audio drivers, still of no avail . Please help me out!!
I know it has something to do with default device , i have changed speakers to default device but still no joy!!
If you connect the headphones to one of the stereo jacks then they will act just like a speaker is pluged in. That's why they have headphone jacks that are for just headphones and when you plug them in it cancels out the speakers.
