[Bug 562310] [NEW] Phonon never uses PulseAudio backend

[Alex Wauck]

Public bug reported:

If I select PulseAudio output for Phonon, the stream coming in to
PulseAudio (according to pavucontrol) comes from the PulseAudio ALSA
plugin, not directly from Phonon.  This may be the reason Amarok crashes
on startup when using the GStreamer backend (see KDE bug #232068).

The problem of Phonon audio output reaching PulseAudio by way of ALSA is
also present in the Xine backend, but this does not cause applications
to crash.  However, the Xine backend does not play certain FLAC files
correctly.

The reason I am reporting this here instead of upstream is that ubuntu-
bug recognizes libphonon4 as being part of qt4-x11, so it seems that
Ubuntu is using Phonon from Qt4.  Colin Guthrie says
(https://bugs.kde.org/show_bug.cgi?id=232068#c3) that the correct Phonon
to use is the one from Gitorious (presumably
http://gitorious.org/phonon), not the one from Qt4.
