[NV79, Realtek ALC272X, Black SPDIF Out, Left] Playback problem

[jazz41408]

Whenever I plug headphones into my laptop I hear sound through the both the headphones and on the computer built in speakers. In order to listen to music or anything through the headphones I have to change the sound manually from the sound menu. (I change it from analog speakers to analog headphones).
