Hi *, I am currently trying to use Phonon and PulseAudio and have the following problem:
When I play some Video with a Non-KDE application like VLC everything is
perfectly directed to the local PulseAudio running on my machine and i have
the expected sound-output.
But when I use a KDE-Application like Kaffeine or Amarok there is no sound
output although the stream is listed by pavucontrol. The volume-indicator for
the stream does not show any activity.
Does anybody have an idea what is causing this misbehavior? Or any hint on
debugging this? When I run pulseaudio -vvv I cannot see any suspicious output
(see below)
Thanks in advance,
Fabian
=== My setup ===
media-sound/pulseaudio-0.9.21.1 was built with the following:
USE="X alsa asyncns avahi bluetooth caps dbus glib ipv6 tcpd udev -doc -gnome
-hal -jack -libsamplerate -lirc (-oss) (-system-wide) -test"
kde-base/phonon-kde-4.4.3 was built with the following:
USE="alsa xine (-aqua) -debug (-kdeenablefinal) (-kdeprefix)"
media-sound/phonon-4.4.1 was built with the following:
USE="alsa pulseaudio xcb xine (-aqua) -debug -gstreamer"
== Output of pulseaudio -vvv when Kaffeine starts playing ===
