I saw crashes... but that was with PolypAudio 0.5, which may as well be prehistory as far as
we're concerned now.
My only remaining concern with PulseAudio 0.9.6 was the CPU chewing because of its `play
silence when nothing is being played' semantics, and that is fixed in 0.9.7.
Nathan was correct above: PulseAudio does indeed appear to be able to imitate *every* sound
server you could possibly imagine, and connect to most of them downstream as well.
