locked Re: Received Audio Level scale floor different with different sound cards

I have the same exact situation. Just little back ground: I was
using a SIIG USB/Audio adapter (I have no clue which audio chip it
implements). About two Windows updates ago, something weird
started occurring. Occasionally and intermittently, the WSJT-X
volume indicator go to 100 and get stuck there. There would be no
decodes when this happens. I tested with Fldigi and the same
thing happened. Restarting either application clears the issue
(for a while). It appears the driver Windows installed and the
SIIG chip don't get along very well.
So, I switched to a C-Media USB/Audio adapter. I then found the
exact same thing as you have reported. With the level set to
zero, no decodes but WSJT-X reports a value of 40db. This does
not happen with the SIIG adapter. When the SIIG adapter level is
set to zero, WSJT-X reports zero (and obviously no decodes).
Note: nothing was changed but the adapter, not even the USB port.
