Actually there is. it's a flag when opening the sync for recording, that
only does PEAK detect rather than a full read.

This should be done in pavucontrol, but IIRC it's not done in pavumeter
(because it's really old).

I could probably add a command line switch that disables the vumeters
easily enough.
