Audio gst bug workaround.

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.

Hi.
Lawrence Anthony
Are you using SDI input? Can you watch video with "gst-launch decklinksrc mode=11 ! ffmpegcolorspace ! autovideosink"?
In my Intensity Pro card I can not get audio if I am not getting video too[1]. You may use a video fakesink [2].
