It does not directly address your need, but I think that
pulseaudiovolumecontrol (pavucontrol) is almost essential, and really
should be installed by default with the pulseaudio system.

In the realm of broadcasting and commercial sound, the function you are
describing is of the general category "ducking" (as in "duck your head so
you do not bump it on the obstruction ahead"). But ducking typically
reduces the level of the primary audio stream, rather than completely
muting it.
You may find an inexpensive hardware solution; check broadcast suppliers
such as Markertek, bswUSA, and FullCompass.
Because "dead air" is anathema to a broadcaster, there are silence
monitors which automatically switch to an alternate audio source if the
primary source goes silent. One of these might serve your needs.
Utility modules of this sort for audio are widely used and tend to be
surprisingly inexpensive.
