Overall, I get the impression that keeping the 'ducking' is a good
thing, so I'll go with that. It was also the consensus on IRC.
As for voice while paused, I do not promise this for a 3.0 feature, as
it will involve one of many Bad Things. The penalty choices for adding
voice while paused basically amount to: ~512k of RAM _and_ one of:
between 0 and 1/4 second of lost audio, between 0 and 1/4 second of
re-played audio or some very complex partial pcm buffer DMA chunk logic.
None of these sounds very attractive to me, so voice while paused is
probably out until someone else either does it or comes up with a
brilliant way to do it.
