** Description changed:
- I ran the audio test of checkbox on my dell inspiron 1525 (no headsets
+ [Impact]
+
+ The following problem happens on systems that don't have gconf gstreamer
+ elements (or they don't work because the desktop environment doesn't use
+ gconf):
+
+ "I ran the audio test of checkbox on my dell inspiron 1525 (no headsets
or speakers connected). When testing the internal speakers of my laptop
no sound could be heard at maximum volume. Usually I can hear system
- sounds, music, ... etc.
+ sounds, music, ... etc."
- ProblemType: Bug
- DistroRelease: Ubuntu 12.04
+ This is fixed in development by replacing the gnome-centric (and
+ deprecated, since gnome has moved on to using gsettings)
+ gconfaudio{sink,source} by the more generic autoaudio{sink,source}.
+ These are better at detecing the underlying elements and enable checkbox
+ audio tests to be run on non-gnome desktops.
+
+ [Test case]
+ - Either remove gstreamer0.10-gconf package to mimic a Kubuntu system, or
install Kubuntu (a virtual machine works fine).
+ - Ensure gstreamer gconf elements are not present; this command should fail
with "no element gconfaudiosink":
+ gst-launch-0.10 "audiotestsrc ! audioconvert ! audioresample ! gconfaudiosink"
+ - Run checkbox
+ - Select only the audio tests.
+
+ Expected result:
+ - Tests produce audio
+
+ Actual result:
+ - Tests don't produce audio
+ - Some traceback may be visible in the .cache/checkbox/checkbox.log file.
+
+ [Regression potential]
+ autoaudio elements use an autodetect library that's part of
gstreamer0.10-plugins-good, so as long as this is installed, it should work for
any user. Conceivably, a very heavily modified and tweaked installation may
"fool" the autoaudio element into selecting the wrong audio source, but this is
highly unlikely. In extensive tests done in the certification lab, these
changes have proven to be very reliable.
