If I mute all the Hw inputs, I still see the dull reading on the meters but no, the monitor doesn't send anything to main out (obviously). Yes, I've disconnected all inputs and shut off the mixer but I still see the slight green background noise on the envy24control meters. I've switched input gains from on the 1010 rack module as well, no difference. .... and yes, all channels consistently. Could there be a difference in the drivers between the 2496 and the 1010... or maybe between 32-bit and 64-bit? I guess my next course of action is to simply grab the 2496 out of the test machine and toss it in here to see if there is noise or not. > > I did have a 1010 unit which started getting intermittently noisy on > some channels, and eventually all channels.

I've been making music with the 1010 for a few years now and would hate to have to give it up. I'm spoiled with the 8 inputs. thanks, David _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
