decklinksink doesn't work with audio only pipeline, works with video only pipeline

Hi,

I'm using blackmagic sdi card and trying to get audio only pipeline as
follows

gst-launch-1.0 audiotestsrc ! audioconvert ! decklinksink mode=11. This
doesn't work. Just hangs after prerolling

But gst-launch-1.0 videotestsrc! videoconvert ! decklinksink mode=11 works
with blank audio

Any guesses here? It it because audio pad is blocking but video pad isn't?
I'm not sure, just guessing :)
