Bug#570519: Does not take into account GConf settings

Package: gstreamer0.10-plugins-good
Version: 0.10.17-1
File: /usr/lib/gstreamer-0.10/libgstautodetect.so
Severity: important
I have an integrated sound card (AMD HD audio, hda_intel driver) that
behaves a bit strangely with ALSA, but this sounds intentional. There
are two devices in /dev/snd: one corresponds to the analog output, and
the other to the digital output. There is also a checkbox, that I can
make appear in gnome-volume-control.gstreamer, that switches betwen
analog and digital output.
Depending on this checkbox, regular ALSA applications (such as xine or
mpg321) use the correct output without any configuration.
With GStreamer, though, this is not the case:
gst-launch-0.10 filesrc location=blah.mp3 ! mad ! audioconvert ! audioresample ! alsasink
→ no sound in digital output.
I have to specify the hardware device by hand:
gst-launch-0.10 filesrc location=blah.mp3 ! mad ! audioconvert ! audioresample ! alsasink device="hw:0,1"
→ works fine.
So, I just force the GConf setting using gstreamer-properties, and the
following works:
gst-launch-0.10 filesrc location=blah.mp3 ! mad ! audioconvert ! audioresample ! gconfaudiosink
→ this works fine too.
However this is completely ignored by the “auto” audio sink:
gst-launch-0.10 filesrc location=blah.mp3 ! mad ! audioconvert ! audioresample ! autoaudiosink
→ no sound.
I’m not sure this is only a GStreamer bug, since no sound at all comes
from totem and rhythmbox, either, and by reading their code they should
be using gconfaudiosink if available. In the end, there might be several
bugs hidden here:
* alsasink being less clever than regular ALSA applications to
detect the correct output
* autoaudiosink ignoring gconfaudiosink entirely (but maybe this
is intentional)
* totem and rhythmbox not using gconfaudiosink correctly (but
maybe this is actually a playbin2 issue)
If only totem & RB actually require fixing, I’d be happy to do that, but
I’d appreciate some GStreamer insight, because it still sounds like
black magic for me.
