[Dell Latitude Black Headphone Out] Audio from both headphone and speaker

[waqar baig]

My headphones are detected when plugged in.
But when I choose headphones from sound setting, the audio still comes from speaker and headphones.
This happens only when its a 3.5mm headphone jack.
Works fine with a usb one.
Please help.

Thanks,
Waqar Baig
