Audio GetComponent<AudioSource>() not working + Microphone.devices is empty.

I'm trying to make voice recognition work in my unity game. To do so, I need to use a microphone to record a 1 second command when I press a key (let's say V).

I start off with:
private AudioSource mic;

I then get the AudioSource component, and then try and get the names of all available microphones, where microfone is a string.

mic.GetComponent<AudioSource>();
foreach (string device in Microphone.devices)
{
//setting the first device as the default.
if (microfone == null)
{
microfone = device;
}
options.Add(device);
}

Unfortunately, the for loop never iterates, meaning that Microphone.devices is empty.
I also believe that mic.getComponent isn't working either.

When V is pressed I call a function. It works down until it hits mic.Stop().
I use mic.Stop() to ensure that it isn't already recording when I start it again.

Once V is pressed, it attempts to execute 'mic.Stop()'. The game then freezes (it's in some sort of infinite loop?)

In Edit-->Preferences-->Audio I've made sure that the Disable Audio box is unchecked. Is there a reason that anyone knows that Unity isn't seeing the available devices? If anyone knows, please let me know.

I'll be digging in the meantime

Thanks,
