Howdy All, was a solution ever found for this issue?:

I seem to be experiencing the same thing. Ran thru steps 1 to 4 as per Noel's advice, but no luck. In RealBand, I can see the VU meters moving, there's just no sound. BIAB plays fine, and the exported wav files play fine in windows media player.

Thanks in advance, J
