Hello, I wanted to listen to some music off of my phone and accidentally plugged my phone's 1/8" into the headphone jack of my laptop (meaning to plug it into the mic jack) and now I have a constant crazy echo/feedback that I can't seem to get rid of except by muting everything. I can't use my speakers at all! Has anyone had this happen, what did you do?!
go to sound setting and decrease the volume of microphone. however your headphones are in the wrong jack.
