Muffled sound after changing Mic

Hello there,

I'm having a bit of troubles trying to fix my in game audio, which sounds muffled and very far.

I just changed the headphones from Logitech H800 to Logitech zone 900.

I checked and tried every possibile solution, drivers, audio setups, repair the game feature etc, but noone seem to work.

The only thing that makes me play the game with the normal audio is switching the mic input to a different source in the in game audio panel, but in this way I'm not able to speak with the headphones mic I just bought.

Any help would be apprecciated.

Thank you all.
