No, PA will only send audio to the device you want. We do have a
"combine" module that creates a virtual device that then outputs to all
the others, but this is very much an option.
You can disable devices using pavucontrol or the Gnome and KDE tools.
With pavucontrol see the "Configuration" tab. Each card should have a
profile selection dialog, you can turn the unneeded cards to the "Off"
profile to ignore them and the devices should disappear.

Just run whatever program you are testing with "pasuspender -- myapp"
rather than just "myapp". This suspends PA until the application exits.
That said, unless you pick a very specific alsasink device, it will
likely use the "default" alsa device which is, in turn, likely to be
routed to PA!
