Fedora 8 Released
Cat in the Hat writes "Fedora 8 has been officially released. Ars Technica has a run-down of what's new in Fedora 8, including the PulseAudio sound daemon, Nodoka visual style, and a new authentication system. 'Another major change in Fedora 8 is the new PolicyKit authentication system that makes authority escalation more secure. Instead of providing root access to an entire program when it needs higher privileges, PolicyKit makes it possible to isolate individual operations that require higher privileges and put them into system services that can be accessed through D-Bus. Another advantage of PolicyKit is that it will give administrators more control over which users and programs have access to individual operations that use escalated privileges.'"
Thankfully, it does appear that PulseAudio is the One True sound server that we can all finally agree on. It emulates esd, OSS, and ALSA, so legacy apps like Flash and your smartphone work. It supports hotplug of audio devices, including networked ones (using Zeroconf even). It supports synchronized output between multiple devices, even when those devices use different sampling rates or have out-of-sync clocks (it resamples automatically). It has a zero-copy low latency architecture, taking advantage of the latest high resolution timer and real-time scheduling capabilities in new Linux kernels (when available), and it supports latency measurement for sound/video sync even when high latency is unavoidable (such as over a network). It has a modern user interface that provides per-application volume sliders like Windows Vista, and allows on-the-fly routing of audio to devices, including "saving" audio streams to another device if the device they are using is unplugged.
The guys behind PulseAudio really "get it". They even decided to drop their typically-awful open-source project name "PolypAudio" in favor of the infinitely better "PulseAudio", for wider acceptance. You've got to give them points for that; the GIMP could learn a thing or two from them.

Oh, and I forgot to mention that PulseAudio has aspirations to become "Compiz for audio", providing earcandy effects such as surround-sound positioning for on-screen events (so sounds from a window on the left of the screen come from the left speaker, etc) and muffled sound from background windows (so the Flash ad in Firefox's background tab doesn't blast your eardrums and the new-mail notification doesn't sound over the movie you're watching full-screen).
