what is the microphone device?

[Rakotomandimby Mihamina]

Hi all,
Using default Ubuntu, i want to capture raw input from microphone jack.
(I plugged my iPod in it, with low volume, I have no "Line-In" input)

The goal is to stream it via VLC, so i need the input device in order to:

  $ cvlc /dev/input_device --sout [...]

Thank you for any help.
