How this can be possible that, I am not able to see speaker built in option in sound Output option.
MacBook, macOS 10.14
Do you have something plugged into the Headphone port?
Hmmm. If you have a wooden toothpick or other small non-metallic object you could see if gently poking into the jack frees anything that may be lodged inside. It's probably safer to have it looked at by Apple or an AASP.
What do you see?
this only.
Nope, But I think there is a Silica ball.
I am not able to see my speaker builtin option in Sounds output option., and in speaker is not working.
