udev was primarily developed by GregKH. Though udev is now part of the systemd tree it is an independently-developed component that is one of the fundamental building blocks of a Linux system.

Meanwhile, Pulseaudio's user-facing problems were threefold -- Bugs in hardware drivers, bugs in ALSA's user plugin system, and horrendously buggy applications. Oh, and it was still a vast, vast improvement over what came before. (I say this as someone who has written a decent amount of audio code over the years..)

This is not unlike NetworkManager, which exposed the inconsistent behaviour of wifi drivers supposedly implementing the same Wireless Extensions interface (and the even more inconsistent event interface) and how every single WEXT client had to use device-specific hacks to ensure consistent behaviour.

I find it sad that the folks who put forth the effort to sanitize core infrastructure bits are blasted for all of the bugs they uncover (and fix!) in the process, while those same voices complain about how Linux isn't ready because things aren't transparently integrated and fully tested like $somecommercialos. This work doesn't just happen, and there are frightfully few people with the technical chops and skin thick enough to accomplish this.

Wasn't one of the somethings that came before something that had per-application mixing, a consistent cross-platform API (and cross-platform implementations), existing application support, and precise, lower-latency mixing? i.e. most of pulse's features, sans network streaming?

If you're thinking of JACK, it is a little on the high end and complicated for just getting mplayer to play audio at the same time as notifications. Pulseaudio works with JACK for handoff IIRC, so they can cooperate. If you're thinking of OSS4 or aRTS, I think those are pretty much dead in Linux-land.

I was thinking of OSS4, which is both still developed for, and still quite usable in Linux. It's just (sadly) no longer the default, in large part due to self-inflicted wounds.
