Audio gst bug workaround.

[Lawrence Anthony]

I am trying to get around a certain gst bug so I can finish my project and am hoping that an audio expert can point me in the right direction.  My pipeline is pretty straight forward at this point:

gst-launch -v -m decklinksrc mode=11  ! alsasink

Does anybody know of a way to get around this bug?  I have tried quite a few combos of audioconvert but nothing seems to work.
