Pinned down the problem with the audio bug. (small solution for some)

In the public test, those of us who run windows 7 systems, kept having a problem with the audio and now also in 0.7.1

I just went through all of my soundcard options trying to find a way round it and to pin it down. (Which I have, a bit)

It seems that the bug is active if you run the game through headphones, 5.1 and 7.1.

But if you have a soundcard that can change the audio to Stereo (2.0/2.1) the audio is crisp and clear, no out of sync/weird sounds.
