I looked at a Win11 laptop i have and tried plugging in a headset. The LT is an ACER with single, combo audio jack and REALTEK drivers/system. When it sees the headset plugged in, it asks for verification of the device types plugged in and has drop down menus to select Line in/out, speaker, headphone, etc. You may need to set your mic as a Line In device to turn off the mic dc bias supply. To avoid having to always switch to them, you need to set your Line In/out devices as the default devices and enable them in the audio settings panel, which should pop up when the devices are plugged in and, also, be accessible from the task bar audio widget. There are also drop downs to select Mono audio which might be necessary and don’t forget to adjust the PC input gain so WSJTx’s rx meter reads in the 50-60 range.
The adapter cable you got is probably electrically right, but should be easy to test (multi-meter, scope, etc.) if you look up your PC’s audio jack connections.
