[pulseaudio-discuss] Routing sink to source

Since years now I successfully use the way you mentioned in "P.S.". I play
to a null sink and record from its monitor.
I'm not sure why app02 should not be able to connect to this monitor. If
app02 is recording from PA in general, independent of "from where", then it
should show in pavucontrol in the "recording" tab. There you can set it's
input source to the null sink monitor where app01 plays to.
