I agree with ScottH that it sounds like the volume punch-through is set in a way that differs from what you want, or perhaps only set for certain devices. As I pointed out in the thread ScottH found, you have to set the volume punch-through on each device - punch-through is not a global setting. If some devices don't have punch-through set, the volume controls will attempt to control the volume on that device rather than on the 950.

Also, before doing a full reset, I'd consult with Outlaw to make sure there's not a better solution to your problem. I say that only because I don't know what the device code is to tell the remote to operate the 950 from the "AUD" device.
