So instead of fixing the remaining problems with pulseaudio (which works fine for many people) one should start creating a new audio system, where other people will have problems with (I doubt it will be bug free for all people from day 1 on)?

It's a shame that people that have a fixed audio setup (two speakers, nothing else?) don't see that with pulseaudio the linux audio system is actually usable the first time. I used to boot back into windows to watch movies and not because of video acceleration, but because of audio problems with surround sound setup or to be able to switch the sound to a tv connected via HDMI.
