Audio gst bug workaround.

[Ruben Gonzalez Uvigo]

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].

[1] gst-launch-0.10 decklinksrc mode=720p5994 connection=component
audio-input=0 subdevice=1 name=a ! alsasink sync=false a.! queue !
ffmpegcolorspace ! autovideosink sync=false
[2] gst-launch-0.10 decklinksrc mode=720p5994 connection=component
audio-input=0 subdevice=1 name=a ! alsasink sync=false a.! queue !
ffmpegcolorspace ! fakesink
