The mic input has never worked

I bought this card because I needed a TOS output. This works properly until 24/192 and I use it to attack an external converter. I am therefore not able to comment on the sound quality of this card.

The problem is that eventually I wanted to use it for the game, and I never managed to get a microphone that is also fully recognized by the mic input of motherboard. I once had a Larssen effect at the start of Windows 7, which leads me to think that the card is not defective but the driver just does not. Note that even the famous free driver does not solve the problem.
