I decided to test PulseAudio on Gentoo since someone claimed the reason
PulseAudio has a "it blows chunks" reputation because of Ubuntu shipping
it with a broken configuration.
So, I did:
USE="alsa pulseaudio -oss" emerge -auDNl --with-bdeps=y world
This installed PulseAudio and rebuilt all applications to drop OSS
support and use ALSA or Pulse instead.
I also took a look at this:
http://en.gentoo-wiki.com/wiki/PulseAudio
and did the "usermod -a -G plugdev pulse" thing.
I rebooted with an ALSA-enabled kernel and with OSSv4 completely
removed. But it doesn't work; everything can use ALSA OK, but not PA.
For example, "mplayer -ao pulse video.mkv" says:
socket(): Address family not supported by protocol
What now?
