Xbox 360 Controller PC audio compatibility

I want to get 2 Xbox 360 controllers for my PC to play split screen games on the big screen. I have looked everywhere and can't find the answer to this question. Do audio jacks on the bottom of the Xbox 360 controller work while in use on PC? Is it just set up as one feed to the wireless hub, then distributed to the controllers? 

they work and are detected by windows. I set mine up to be used for just mic and i run the audio through my DAC

Thanks, wasn't sure if all the functions of the 360 controllers were supported by Windows.
