Just to be clear, what I am proposing is to disable monitoring sources
only for the case where a sink supports compressed data. Null sink
doesn't so there's no change of functionality.
You could push silence instead, but that's a pretty much a waste of
resources; I don't see any need for monitoring for compressed data at
all for a pass-through mode... If you need to decode, it has to be
