Wired earphones not detected as output device by default

Hey Guys,

I have newly installed Manjaro Gnome and I am absolutely amazed by its simplicity and fluidity in performance.

But , When I connect my earphones into the 3.5 mm jack , the system doesn’t change its output source automatically . Each time I have to open the Pulse Audio Volume Controller application and change the output to my earphones manually.I know that its not that big of a problem but still if there is a way to fix it,please do let me know.
