[gentoo-user] Can't get PulseAudio to work

[Nikos Chantziaras]

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?
