I have a Level B signal coming into my Corvid 88 card. It is read fine by AJA Control Room, but once in vMix, the signal drops regularly. It causes all audio busses to flash off and on at the same time. I see a picture for a moment before the input reacquires, dropping to black, then restoring. This cycle happens about every 10 seconds. Sometimes longer, sometimes shorter. I changed the signals to Level A and it’s solid for now. Is there any way I can keep the system on Level B?
