Info :

These two pipelines have failed (silence no warning) :

* gst-launch-1.0 -v alsasrc device=hw:XFi ! capsfilter caps="audio/x-raw,
format=S16LE, rate=48000, channels=2" ! audioconvert ! audioresample !
capsfilter caps="audio/x-raw, format=F32LE, rate=48000, channels=1" !
jackaudiosink name=src client-name=xfi sync=false connect=none

* gst-launch-1.0 -v jackaudiosrc client-name=julia name=sink connect=none !
capsfilter caps="audio/x-raw, format=F32LE, rate=48000, channels=1" !
audioconvert ! audioresample ! capsfilter caps="audio/x-raw, format=S32LE,
rate=48000, channels=2" ! alsasink device=hw:Juli sync=false

But this pipeline has not failed, although it is known to fail:

* gst-launch-1.0 -v jackaudiosrc client-name=xfi name=sink connect=none !
capsfilter caps="audio/x-raw, format=F32LE, rate=48000, channels=1" !
audioconvert ! audioresample ! capsfilter caps="audio/x-raw, format=S16LE,
rate=48000, channels=2" ! alsasink device=hw:XFi sync=false

This mean it's too early to draw a conclusion about other pipelines wich still
have time to fail.

This interesting because we have one example of "alsasrc ! something" pipeline
failure. It seems more difficult to observe.

Yes I can. :)
