I have a pair of apple headphones and when I plugged them into my old samsung laptop, they used to work. But when i plug them in to the Dell laptop, It asks "Which Device did you plug in?" and i have to choose between Mic in, Line in, Dell devices,Headphones/Headset, External speakers, or surround front. I choose Headphones and the sound output works, it plays the audio to the buds but when i try to use my mic it doesn't pick it up. I tried going to playback devices and select a default mic but no mic is added when i plug in my headphones. Also when i put listen to this device I can use an internal mic but it cant be used when I want to actually use it.
