Re: nvda and volume change
I sense that something's afoot here, as this topic, Volume issue, which is very similar in nature came up on the Chat Subgroup (even though it would have been fine here - I hasten to add) several days ago.
I zeroed in on the same likely potential cause as Mr. Stewart. There was never any confirmation regarding whether ducking was involved, though.
