Great. Can you please test the following:

gst-launch-0.10 audiotestsrc num-buffers=1000 ! audioconvert !
"audio/x-raw-int,width=32,depth=32" ! wavenc ! filesink
location=test1.wav

gst-launch-0.10 audiotestsrc num-buffers=1000 ! audioconvert !
"audio/x-raw-int,width=16,depth=16" ! wavenc ! filesink
location=test2.wav

And then run
aplay test1.wav
and
aplay test2.wav
?

Do you get crackling on test1.wav too and not on test2.wav?
