Description jezra 2014-04-30 22:51:38 UTC 
When running `gst-launch-1.0 autoaudiotestsrc ! autoaudiosink`, audioaudiosink will stop looking for an appropriate audiosink if a fatal error in an audiosink is encountered.

This may be a very fringe case, and my system is an ARM device with kernel 3.14.2 and gst-plugins-good installed.

gst-launch-1.0 autoaudiotestsrc ! autoaudiosink gives me the error: 
FATAL: cannot locate cpu MHz in /proc/cpuinfo

`gst-launch-1.0 autoaudiotestsrc ! alsasink` works just fine, however, and removing gst-plugins-good resolves the issue.

what prints
FATAL: cannot locate cpu MHz in /proc/cpuinfo
can you run this under gdb and get us a backtrace. We run element registration in a separate process to catch such issues, but if any element calls exit() at runtime, there is nothing we can do here.
Comment 2 jezra 2014-07-16 22:55:15 UTC 
Sadly, I am no longer in possession of the ARM system where this was showing up.
Comment 3 Stefan Sauer (gstreamer, gtkdoc dev) 2014-07-17 06:53:45 UTC 
I am quite certain, one of the sink elements or the libraries it uses was calling exit() :/
I am closing the bug.
