Siberia v2 Mic headphone adapter not working after restore Macbook Air
So i restored my macbook air a couple of weeks ago and i have backed up all items and documents from before. And before i had restored my mac i had a Siberia V2 Headphone+mic adapter because there is just 1 headphone jack, it worked perfectly but now it doesn't work, only the sound out is working and i've tried to turn the mic on but it still doesn't work. The only option for microphone in settings is the default microphone in the mac. My Macbook air is from mid 2012.
MacBook Air (13-inch Mid 2012), OS X Yosemite (10.10.2), School computer
