It also means, if you will forgive the heresy, that the sound quality is much better. This really shocked me, to realise how poorly PulseAudio resamples. The main downside, beyond the initial one of having to get all my applications working properly, is that OSS4 won't suspend nicely.

There was no choice. OSS was a) proprietary, and b) neglected. If Linux wanted
sound something else had to be done. That OSS has come roaring back is great.
Competition is always good to spur both sides to do better.

Well, not infinitely but I learned how to program oss in a few days to write
my sound card testing program. Oss had some documentation. I have occasionally
looked at rewriting it for alsa and have always shied away. There is no
documentation, and trying to disinter what I need to do from example programs
is too frightening.
