Headphones, Speaker playing simultaneously

Hi, I am new to linux, The speakers on my PC work fine, but when I plug in headphones (which also work fine) I expect the computer speakers to mute. They don’t. How can I get my speakers to mute automatically when I plug my headphones into the jack?

and if you have the same chipset as , this could help
