Title:
  Microphone works, but line in not on laptop with one jack for line in
  and line out

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  I have an interesting issue with Ubuntu. I have a laptop that has one
  jack for line in/microphone and line out/headphones.

  This the reason why I bought a spliter like in the attached image.

  >Splits one 4 pines jack into two jacks: micrphone and line out

  I have an external studio microphone and headphones with the
  micrphone.

  ## Case 1 (Working)

  If I connect the micrphone of headphones to spliter that is inserted
  into my laptop, I can record my micrphone.

      HEADPHONES MIC ----+
                         |
                         +------- LAPTOP
                         |
      HEADPHONES OUTPUT -+

  ## Case 2 (NOT Working)

  If I connect another an external hardware (for example a piano) to the
  splitter, I cannot record anything... This is the issue. How can
  Ubuntu recognize if there is a headphones micrphone or an external
  hardware that is NOT a headphones micrphone?

      PIANO  ------------+
                         |
                         +------- LAPTOP
                         |
      HEADPHONES OUTPUT -+

  ...and the question is how to fix this? I want to record my piano
  using my laptop: through line in.

  Would be the splitter an cause?

  Do I really need a hardware that I don't have (like an USB recorder)?

  **Update**: tested with Windows 8 on same laptop. It works properly...
  (Un)Fortunately, I am an Ubuntu user, so I will not go back to the
  Windows world... Still searching for a solution on Ubuntu.

  I asked this on AskUbuntu and no solution found...
