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 below:
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?

Update: tested on 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.
