Yes, you would need a special cable to cross-connect with the microphone
input. If you had two of the 4-conductor splitters, that might work.
Yes, I already ordered another USB->Audio adapter but it won't get here in
time.
I basically want to pipe the audio Comp1-out -> Comp2-in, and

What is the purpose of this? Are you wanting to hear something or is it
some sort of communication channel between the computers?
I didn't want to get specific as it's not a use case for many others
outside of ham radio. Digital communications with ham radio is done with a
sound card and the audio is sent to the radio and transmitted over the air
where it is then captured and interpreted by the receiving station. I want
to simulate this in a meeting environment with two laptops without radios.
The jack on my new laptop seems to support the 4 conductor jack (stereo
audio and mono mic) but I don't have the proper cable to split it out.
Regardless it's always suggested to use a dedicated sound card for this
purpose so general system sounds do not get transmitted over the air, so an
additional USB->Audio adapter is the correct long term plan.
Thanks,
