my 970 was purchased last september from Outlaw via ebay with the current firmware on it, i have had the no audio problem, it didnt happen the first few months but it seems to happen more lately. i also noticed there is a glitch which caused a high tone high volume warble. ive since discovered that the 970's pink noise generator has a very narrow band, ridiculously so, and that it won't hold even volume between the two main channels with volume changes. a friend of mine is an electrical engineer and he has basically done most of this research on my 970 in his nerd lab. i did suspect something was wrong and asked his opinion which lead to him taking my unit for few weeks, but i am not to credit with these results for its all over my head.

so buyer beware.
