Murray,
What microphone is your K2 wired for? Check the microphone
configuration header on the front panel if you don't know - the info on
plugging the header is in the KSB2 manual.
I don't know the wiring for that Kenwood adapter, but it may be
connecting to the wrong pin for your K2 mic wiring.
If your mic is configured for either Elecraft or Kenwood, it should work.
Have you checked the speaker (or Line) output settings in the computer?
They may be too high.

I have a K2 with the KIO2 and KSB2 options. I am using WSJT-X with a
USB/serial adapter connecting my PC to the KIO2 for rig control. I
have a male-male 1/8" audio cable connecting the K2 headphone jack to
the PC microphone input. With this arrangement, I can receive FT8
well. It receives so well that I want to try transmitting even though
I only have 5 or 10 watts from the K2.
I then have connected another male-male 1/8" audio cable from the PC
headphones connector to the K2 microphone input on the K2 front panel.
I make this K2 connection using a Y-cable with a Kenwood type mic
connector on one end and 1/8" female connector and 1/4" female
connector for a PTT footswitch (not used for FT8). This is actually an
accessory cable for Heil headsets.
The second I plug in the audio cable to the K2 microphone Y-cable, I
immediately lose synch and the RS-232 connection fails. I thought
incorrect audio level might be causing a problem but I've tried many
different audio input levels with no luck. I don't understand why
making the audio input connection would affect the rig control
connection.
I should note my PC has a combo audio jack so I must use a Y-adapter
to access both the input and the output audio. This adapter works fine
on FT8 with a different transceiver.
