If an ncurses interface was written, please use libpulse and not a
command line wrapper around pactl... it'll be far easier anyway :p

Ahh but Pulse piggy backs on to the X11 protocol so that if you ssh to a
remote machine and run an app, you will get both the display and the
audio that app produces on your *local* machine.
I guess your expectation is understandable, but by the same token, more
people prefer things to work seemlessly.
If you want to know more about how this process works, see here:
You can always ensure that you run "pax11publish -r" first and that way
a remote PA daemon will be used instead.

Bear in mind that even if you do ssh to a remote machine, if the X11
properties on the root window are set as they are by default, then pactl
will control the PA deamon on your local machine via the network
protocol. pacmd will likely not work as it uses a different interface.
If you read and understand the above article, this should make sense :)
