h264 update message breaks audio?

I seem to recall this may have happened to me once before. The audio from SDI stops working - the video continues, but no audio. Updated the software, and working again, but not before I tried everything things re: switcher

It happened again just now, with 9.5.3. I cannot correlate exactly that this update message causes the audio to break, but I know the audio works because it was working prior to me stopping the capture.

Anyone else experience this issue?
