Jim,
I am going to assume you are running Windows.
To the computer, the "soundcard" in the K3S is little different than any
other USB soundcard, except the 'external box' happens to the inside the
K3S.
That means you have soundcard levels in the computer which can be adjusted.
Right click on the speaker icon near the clock and first select Playback
Devices
In the window that opens, select the CODEC for the K3S and click in the
Properties box at the bottom right. Once Properties open, click on the
Levels tab. Reduce the Playback level enough so you can obtain a
workable LINE IN level on the K3S and still achieve an ALC meter reading
of 4 bars with the 5th bar flashing when you "transmit" with the
software application. Mid-range settings of the LINE IN level will give
you more granularity and make the required ALC setting more easily
achieved. Use TX TEST while making those adjustments so you don't
actually produce any RF.
Going the 'other way around', adjust the K3S LINE OUT level and the
soundcard recording level to achieve reasonable values for each - there
is nothing wrong with a line out setting of 5. Try not to use a LINE
OUT level of 10 or more.
If the soundcard shows both MIC input and LINE INput, select LINE. If
you must use the MIC setting, make certain the mic preamp is not tuned
on. Adjust the K3S LINE OUT and the soundcard Line In (or Mic) slider
to achieve a good colored waterfall display in your software application.
Using the internal CODEC (soundcard) in the K3S should be no different
than using most any other external soundcard.

The Windows recording and playback levels of the soundcard in my K3S seem to
both be very sensitive. For RTTY, other digital modes, and voice messages I
have the level set at only 5 for recording and 18 for playback.
I have my LIN OUT in the K3S set to only 5 for RTTY reception (recording)
and to 14 for digital mode TX (playback).
