Solved! My headphone (using jack 3.5 mm) output is working but not the input (microphone)

[deovl]

So I just realized that every time I plug in my earphone with integrated mic, the input was always using only my built-in laptop microphone. so the sound quality that I recorded has always been bad.
The output works perfectly fine.

I've tried to follow some of the instructions like setting the privacy on, etc. but still don't get any answer to my problem.

Also checked to plug in my earphone to my friend's laptop. both output and input work fine.

which laptop are you using?

Set the external mic to default recording device in the windows sound manager
