hi guys.
so i got this problem with the line in - i plug the guitar, and i just can't hear in the computer the sound! and its don't recording the guitar sound.
in the past i just plunged in the guitar and i could hear and record, but now its just don't do it!
i checked, and the problem is not with the cables or anything... everything is normal except that it's act like the guitar isn't there.

obviously your line-in is deactivated/muted. go to your windows sound control panel and check your line-in settings.
