--- Comment #6 from Martin Jürgens martin@gamesplace.info 2007-11-19 04:32:39 --- PA will offer a good latency as soon as some kernel patches flow in. If you need more information, please ask.
I understand your arguments and I think that currently, you are right.
But then, there should be at least some communication with the PA devs in order to make it possible to use Wine using the ALSA backend.
The more distros switch to PA (and they currently are doing so), the more users will complain about "no sound in Wine".
