Comment:

 Ah! The "Not Enough Bandwidth" is the reply in case the AEX is already in
 use. A sink is still created in that case, but it does not work. Maybe it
 would be a good idea to not create a sink after that reply...?

 As previously reported I had everything working with mpd+pulseaudio
 +module-raop (fixed config, not autodetection, as it seems broken with AEX
 7.4.2). That was on my desktop PC... then I tried the same on my
 fileserver, which is supposed to become my musicserver. Same Ubuntu, same
 pulseaudio, same mpd, but... skips as described by others in this ticket
 and those logs:

 {{{

 I tried playing with fragments and size, made sure pa is using high prio
 and realtime scheduling, checked network speed; nothing helped.

 I tried upgrading from Lucid default mpd 0.15.4 to 0.15.15 from a ppa, but
 that changed nothing.

 To further exclude mpd as a cause of the problems, I configured the mpd on
 the fileserver to use the pulseaudio on my desktop (which in turn uses the
 AEX)... and that worked perfectly!

 So... not working:
 {{{[fileserver+mpd+pulse-output-plugin+pulseaudio+raop] --> [AEX]}}}

 working:
 {{{[fileserver+mpd+pulse-output-plugin] --> [desktop+pulseaudio+raop] -->
 [AEX]}}}

 btw, also working without problems: the ruby raop module using this simple
 stdin-->AEX script:
 http://raop.rubyforge.org/svn/trunk/examples/read_stdin.rb

 sinks look the same on both desktop and server:

                 device.icon_name = "audio-card"
 }}}

 ...i am completely out of ideas what could be wrong... anyone?
