I did successfully get the 15 buck upgrade to v4.0 of VAC (I bought it directly from the author) and could not find the mojo to make it work for me. The only way I could get any audio to MixW was with the audio repeater and that was in snatches (like every 3 seconds a burst would come, then silence again).
The author warned me it was completely different and to not be surprised it did not work. I can use it for audio stuff so its not a lost 15 dollar expense, but if anyone does figure out the mojo, it sure would be nice! Neal - k3nc
