Ahhh.  Of course.

"sound level" RPC in the PA protocol for things just like a vumeter.  Surely 
it's much more efficient for the sending side to send "sound level" measure-
ments than to send the actual audio stream for the receiving side to simply

No, I don't.  Things are wonderful now.  :-)  I would like to be able to keep 
pavucontrol open though, obviously without the vumeter penalty, hence my 
suggestion above.

Many many thanx for your persistence in this Maarten.  I really do appreciate
