I've had 2 970's. The first had the no audio bug, but I sent it back to Outlaw for repair and the problem was fixed. I sold that one (advised the new owner of the fix btw). I've not experienced the no audio bug on my current 970, but right now it's back with the Outlaws for a speaker hiss it's causing. There were certainly some 970's that had (have) the no audio problem and in my experience it was one 1 out of 2, but Outlaw corrected the problem in the one that had it. How many had the problem is anyone's guess.
