With older VMID referenced devices like this one seems to be there's
usually not really any good tradeoffs.  You have to balance audible
noise on the outputs when starting audio, idle power consumption and the
time taken to get the device live either on starting a stream or boot.
Generally for a given device there's a fairly clear optimum and trying
to support multiple options makes things more complex and less robust.
