Hello PulseAudio gurus,

I could use a male-to-male 3.5mm cable, connecting Linux box #1's 3.5mm Output port to Linux box #2's Line-In 3.5mm port. And then play audio on box 1 and hear the speakers playing sound on box 2. I used this : https://askubuntu.com/a/267347. Practically using module-loopback. This works all good.

My software is using PyAudio to read from Microphone input and pipe/yield the recorded audio stream to the internet : https://people.csail.mit.edu/hubert/pyaudio/#record-example

My question is, is it possible to use PulseAudio to pipe/forward Line-In stream to Microphone stream ?

Many thanks.
