Bug Report Failed Initialize audio source

OBS crashed with message:

MMDeviceAudioSource::Initialize(1): Could not create IAudioClient

when audio source (in my case microphone) is disabled or not present in Windows Sound Setting. Many sound drivers have autodetect for mic on front or back panel, so if you just disconnect your microphone, you will be get this error.
I think this may be fixed by checking audio devices before stream start.

Woops, thank you for pointing that out. Yep, you're right, I neglected to make it check to make sure the device is available. I'll get it fixed next version.
