Now, whether the PC's electronics were enabled to take input from the speaker port is another story.
FYI, many current laptops come with an integrated microphone
My laptop has neither cam nor mike, but the guy in the front apartment's has both and I shudder to think what it has the possibility of seeing and I don't believe he even realizes it and it's not taped over! AAAAAH! I DON'T WANNA KNOW!
