I didn't check this, but I guess the tunnel sink doesn't shut down the
stream when it's not in use, so it transmits silence. There's probably
no reason to do that, so filing a ticket for the bug would be a good
idea (if no such ticket exists yet).

What do you mean by "future"? If the mic isn't there yet, you of course
can't record from it...

All devices on host2 should be visible on host1, including microphones.
You can check whether the mic is actually available on host1 by running
pavucontrol and opening the Input Devices tab.

If the mic is there, but your record application still doesn't seem to
get any data from there, open the Record tab in pavucontrol while
recording, and right click the record stream that should be visible
there. The context menu allows you to move the stream to the correct
source. That hopefully solves your problem.
