core: Suspend monitor when a sink enters passthrough mode

Browse source 
In most cases it is expected that clients cannot consume compressed
data from monitor sources, so we suspend the monitor source when the
sink goes into passthrough mode.

Eventually, when the extended API includes client notifications for
changed formats, we should emit a notification on the monitor so that
clients can decide what they want to do when this happens (disconnect or
consume the data anyway).
