[Elecraft] Starving" Fldigi for audio Rx

[paul ecker]

In response to my question on the Win- Fldigi Reflector that I asked regarding waterfall adjustments and the fact that I was seeing no signals on the Fldigi Scope, Dave W1HKD  responded,--- If you need those controls set to the maximum range and lowest absolute signal (or close to it) then you are probably starving Fldigi for Rx audio--
So my question  concerns Dave's comment that I am "Starving" Fldigi for audio Rx.  Do other K3/ Fldigi users when operating in PSK 31 mode see any signals on the Scope view? I have tired adjusting the Rx pot on my DK II and Windows - Sounds- Recording -Levels with no change.. in Fldigi. I am able to decode signals.What settings on the K3 affect Rx audio to Fldigi?
(Setup:Win 7 PC, micoHam DKII interface.)
