If you mute all the inputs, maybe even disconnecting the inputs, do
you still get noise? Is it on a few channels? All channels? If you
change the input gains of the 1010, does the noise change? If you
change the output gains of the 1010, does the noise change?
I did have a 1010 unit which started getting intermittently noisy on
some channels, and eventually all channels. It turned out to be a
bunch of bad capacitors in the 1010. It was under warranty, and I
got an exchange unit for it. I didn't have a Windows system to see
if the symptoms were any different. On Linux the bad input has noise
levels bouncing about -10dB on the meters. I have my hardware input
level switches at +4dB, if that makes a difference.
Keep working on this. It'll be worth it....
