Jim,
The audio level settings have finer resolution when set to a mid-range
value. Make sure none of the audio controls (including the mislabeled
"POWER" slider in the application software) are not set near the upper
or lower extremes.
You have at least 3 level controls to consider - the POWER control in
the software, the soundcard SPKR or LINE OUT, and the LINE IN level on
the K3.
As others have mentioned, some soundcards have humps and valleys in
their output response, so the output may vary with the audio frequency.
You can decide whether to live with that or get a soundcard with a
flatter response curve.

K3 original - ALC erratic
Noticeable on digital mode(s?) (FT8). The ALC - set at 4 solid and 5th
flashing - is far more critical than I remember. Seems like I could easily
set it exactly where I wanted it and it would stay there.
