Oh, it's very possible. Just a matter of setting some parameters
correctly. Technically you don't really need separate virtual cards on
the host for each VM anyway. They can all output to the same virtual
cards, and they can all input from the same virtual card. The trick is
making sure the that input virtual cards is *not* the monitor of the
output virtual card which is your situation just now.
You only need two null sinks.

There will be a way to get it working, but perhaps I got the syntax
They syntax works for me :s
Are you running a system wide PA or a per-user PA?
If system-wide then module loading is generally disabled for security
But you can add the commands to your system.pa file
(/etc/pulse/system.pa) or default.pa (/etc/pulse/default.pa) depending
whether you use system wide or per-user.
Try editing the appropriate file and make the following changes:
1. Comment out the line that says:
2. Add the following lines:
load-module module-null-sink sink_name=fakeout
load-module module-null-sink sink_name=fakein
Then restart PA. If it doesn't restart then there is something wrong
with your changes (so best to keep a backup of the file).
Hopefully that'll be enough to get things setup for you.
