I might have to retract that. Occasionally, I'm getting a situation where
a pa_context_set_sink_volume_by_index() or pa_context_set_sink_mute_by_index()
operation succeeds, but the action fails (duly reported by the callback).
When that happens, volume is pretty much indeterminate. At first I put it
down to some unknown action on my part, eg not doing a full clean/rebuild
after application changes. I'm really not sure. There could well be some
subtle issue there.

cheers, Cal
