Hi, yes I am using 5.1.
It has just happened again - I double click the envelope line to add an adjustment point (or whatever it's called), and then drag the point at the very end to the very bottom right hand corner. Then I play the video and there's a burst of sound at the end. Sometimes there's even a gradual fade up between the last two adjustment points. All in all I'm finding it very unstable - sometimes the envelope sets itself visually to zero, but when you play it it's exactly as you left it, I just close AVS and open it again and the envelope is the same as I had it before.
