This may have been a valid concern in 2009; but PulseAudio has grown and is here to stay. Most distributions have adopted it including, but not limited to, Ubuntu, Fedora, and OpenSUSE.
Furthermore, PulseAudio is a system dependency of GNOME3, possibly requiring more work to remove in the future.
If this is the case, then my sugestion would be to sort it out compleatly and clean up the sound-architecture in total, the situation right now is bordering on insane, it is a mess, why can't some leading distros (like min/ubuntu/debian) get together and just deal with it once and for all ?
Suggestion : Set a (one) standard and fix the interfaces, clean nice and working out of the box for all users.
Currently it all seems to be a ptachwork och semi ready and half finished ideas loosly held inplace, just choose ONE and FIX it, go for PA if that is here to stay and growing, just please fix it, work with the others and agree upon a maintrack, personally i do not care what it is, as long as it works.
2012, some 10 years into it's life linux audio is still not fixed, for example, in Linux Mint 12 you have to go into alsamixer (via terminal noless) to get the line-in working (unmute), the same goes for boosting the mic when using skype, then use PA to adjust the system volume, does this sound like a good user experience ?
Sorry for being a bastard, but I just have to get this said, and to have someone listen, linux audio has alot of potential, brilliant soundquality, no DRM mess, low latency capabillity, it is all there, but currently you have to be a professor with limitless patience to sort it out and use it, that's the only thing standing in the way of computer audio world domination, it's been 10 years now, that should be enough right ?
