Unfortunately, line inputs are as rare as serial ports in new computers.

To make JVComm32 work with my M802, I had to connect it to the speaker
jack on the chassis, not the headphone jack. Either not enough power or
too much impedance mismatch.

I would say whatever output you use, speaker or headphone, it will
completely overdrive the mic input on the PC. Use a Line input.
