Intensity Pro 4k RCA Audio Settings

Hi,

I am trying to run the following command on gst-1.0 :

gst-launch-1.0 decklinksrc connection =component mode =17 device-number =0 name = demux ! audioconvert ! queue ! level ! alsasink ! sync =false demux. ! videoconvert ! queue ! xvimagesink sync = false

The RCA Audio gets off automatically whenever I run this command .

Please suggest some workaround for this problem.

Sorry I can't answer your immediate question - I just wanted to point out that the fact you're using "decklinksrc" indicates you're not using the latest gst-plugins-bad. The most recent version has separate decklinkvideosrc and decklinkaudiosrc source elements (and corresponding sink elements) which are intended to overcome video/audio shortcomings associated with the single deklinksrc element.
