Hi Sean,

I took the diagram you made for me[1] and updated it with the PulseAudio 
commands I think I need to implement it:

Steps 1 and 2 were the ones you gave my in your very first reply[2]. 
I've just updated the sink_name and device.description to match the diagram.

Step 3 creates the other virtual sink.  Hopefully I got those commands 
correct.

I'm struggling, however, with the command syntax to create the other two 
loopback modules.  I'm not sure how to craft the sink= option for those 
or whether they are even required.

Any ideas or suggestions for those?

Thanks again.
Samir
