Be careful, when I wrote "only pause and re-playback it", the word "pause" was
not really correct, "stop" is better.

This is what I mean (it works):

pipeline.set_state(Gst.State.NULL)
pipeline.set_state(Gst.State.PLAYING)

This is NOT what I mean (it does not work):

pipeline.set_state(Gst.State.PAUSED)
pipeline.set_state(Gst.State.PLAYING)

I will do this. But for your information, audioconvert and audioresample
function properly with other modules (like jackaudiosrc or jackaudiosink).

I'll try to get a computer with multiple sound cards for doing several
different tests in parallel.
