** Description changed:
- .
+ [Impact]
+
+ When running any job using the alsa_record_playback script from checkbox,
the test fails and an exception with trace is produced. This happens on
installations that don't have the alsasrc gstreamer element, such as kubuntu or
xubuntu. Thus, the test fails
+ even if audio on the system is indeed working properly.
+
+ Due to the high incidence of this bug as mentioned in comment #17, and
+ the fact that the fix is relatively simple, it's worth backporting this
+ so it's available on the latest stable release (13.04).
+
+ The fix was introduced in checkbox trunk revision 2083, it simply modifies
the script itself so it uses the autoaudiosrc element which should be available
in any sane gstreamer installation (with the good set of plugins), and it also
modifies the job definition so that the job won't even run in the unlikely
event that not even the
+ gstreamer*-plugins-good are available, rather than producing a confusing
crash and trace.
+
+ [Test Case]
+
+ - Ensure that gstreamer1.0-alsa is NOT installed. It's not installed by
+ default on Ubuntu flavours such as kubuntu or xubuntu. If you're running
+ vanilla Ubuntu, you can sudo apt-get remove gstreamer1.0-alsa.
+
+ - Run this command:
+ PATH=$PATH:/usr/share/checkbox/scripts alsa_record_playback
+ - Expected result:
+ Sound is recorded from the microphone for a few seconds, then played back
through the speakers/headphones.
+
+ - Actual result: Error Trace as seen in the original report.
+
+
+ [Regression Potential]
+
+ * Not much of a chance for regressions, since the autoaudiosrc source has
been in the gstreamer-plugins-good package since at least Ubuntu 12.10. As
mentioned in the comments, checkbox has been using autoaudiosrc without any
reports of problems in *most* of our audio-related jobs, so this should benefit
from that experience.
+ Checking for the gstreamer{0.10,1.0}-plugins-good packages is a safety net
that may nevertheless cause problems if a user has a version of the plugins
package that contains autoaudiosrc and doesn't match the package names we're
expecting, however this is unlikely for the targeted versions of Ubuntu.
