I am a newcomer here. Apologies if this is not the right forum for this post. I am using the DVEO SDI Master card on a PC and trying to capture/playout a video. The video plays fine but the audio fails to play. This is happening both in Windows and in Linux. Anybody has faced similar issue before? I am using a Blackmagic design Analog to SDI Mini Converter for input and a SDI to Analog converter for output. However the problem persists even if I change the input and output to something else.
